While You Were Sleeping (2017 TV series)

The series opens with Hong-joo waking up from a dream where she hugs and expresses her gratitude to a wounded stranger in a crossroads on a snowy night. Just in time, the stranger in her dream, Jae-chan, arrives in their neighborhood with his younger brother Jung Seung-won (Shin Jae-ha) and moves in a house across theirs.

While working with her mother Yoon Moon-sun (Hwang Young-hee) in their samgyeopsal restaurant, Hong-joo meets a chain smoker whom she dreamed of and was destined to die at a gasoline station. Hong-joo is unnerved when the smoker dies in the way she had dreamed and by another dream in which her mother was destined to die in an accident Hong-joo is about to get into; this pushes her to cut off her hair because she had long hair in the dream.

On his first day at the Division 3 Prosecutors' Office, Jae-chan meets Lawyer Lee Yoo-beom whom he secretly loathes because of a bitter incident dating back to when he was a teenager. One night, Jae-chan dreams that Yoo-beom takes Hong-joo on a date. In the dream, Hong-joo excuses herself to go home thinking that she left the door at their house ajar. As it unexpectedly started snowing heavily, Yoo-beom insists on driving Hong-joo's car and during the drive he gets into an accident in which a policeman is killed. Yoo-beom claims that Hong-joo was driving, dragging her while unconscious into the driver's seat and falsifying evidence. When she wakes up from a coma, months later, Hong-joo is wrongly accused of the accident, and learns that her mother died of exhaustion working to pay the damages claimed by the victim's family. In vain, she protests her innocence to Jae-chan, the prosecutor in charge of the case in the dream, and ends up committing suicide, Jae-Chan being unable to stop her from jumping off the hospital roof.

Although incredulous, Jae-chan learns that he shares the same future-seeing ability as Hong-joo though they do not know why they have to see each other in their dreams. The skeptical Jae-chan thinks that Hong-joo is crazy and he persists in denying the existence of such dreams.

Meanwhile, high school piano virtuosa Park So-yoon (Kim So-hyun), who is Seung-won's love interest, has her piano recital. While being interviewed by the media, her mother Do Geum-sook (Jang So-yeon) faints, causing confusion at the venue. The police and the media see what seemed like footprints on Geum-sook's undergarments while So-yoon's father Park Jun-mo (Um Hyo-sup) tries to cover it and insists that he did not do it. So-yoon realizes that her father, who had been abusive to them, had beaten up her mother again. As Jun-mo is being arrested by the police, So-yoon pleads with Seung-won to pretend that he does not know about her father's cruelty.

Lawyer Yoo-beom takes Jun-mo's case at once and falsifies evidence and testimony to make it impossible to prosecute the case. Goaded by the discreet admonishments from his seniors in the prosecution office, Jae-chan becomes disappointed that he cannot fully investigate Jun-mo's case and satirically declares the case cannot be prosecuted. Knowing that her father will win once again in the case, So-yoon plans to kill her father by poisoning him. Seung-won becomes aware of her plans, though he insists to her that she must report it to the police.

Knowing that their dreams will come true soon, Jae-chan and Hong-joo analyze their dreams and realize that they are related to Park Jun-mo's domestic abuse case, which Jae-chan had declared could not be prosecuted. So-yoon receives a call from her mother. Sensing that something bad is about to happen, Seung-won and So-yoon rush to the Park residence, located in a high rise apartment. Jae-chan and Hong-joo also dash to the residence to stop them.

Meanwhile, police officer Han Woo-tak begins having precognitive dreams after Jae-chan saves him from getting killed in the Valentine's Day car accident. In his first dream while sleeping in their patrol car, he sees himself arresting a high school boy (Seung-won), who was pleading for innocence, and Jae-chan screaming to the police to set the boy free. Just in time, he sees Jae-chan and Hong-joo running through the streets. Sensing that the dream is about to come true, he follows them to the Park residence.

In the Park residence, Geum-sook pleads for divorce, asking Jun-mo to pay for So-yoon's education abroad. Jun-mo arrogantly rejects her offer, but just before he starts beating her up, Hong-joo sets off a false alarm, prompting all the occupants to exit the building. Jae-chan catches Seung-won, who rebukes him for being lax about Jun-mo's case. To hide from Jun-mo, So-yoon and Geum-sook escape to Hong-joo's residence, accompanied by Woo-tak who offers them a ride on his patrol car. Jae-chan, then, decides to reopen Jun-mo's case, despite getting scolded by his chief.

Soon after the ruckus at the Park residence, Woo-tak sees another vision in his sleep. He sees himself and his police partner Oh Kyung-han (Lee Yoo-joon) going to Hong-joo's samgyeopsal restaurant. In the dream, Lawyer Yoo-beom arrives in the restaurant to convince So-yoon and Geum-sook to withdraw their appeal to prosecute Jun-mo so that So-yoon can retain her reputation as a pianist. Frustrated and willing to give up her career for their family to be peaceful again, So-yoon attempts to injure her hand with a chopstick but Hong-joo interferes and gets her hand impaled instead.

Woo-tak is amazed that his dream is already happening exactly as it is, except that he was having a meal with Jae-chan, not Kyung-han. Jae-chan overhears the conversation between Yoo-beom, So-yoon, and Geum-sook, and just before the accident happens, Jae-chan intervenes in the argument and promises So-yoon and Geum-sook that he will prosecute Jun-mo in every way he can. Woo-tak learns from Jae-chan and Hong-joo about their precognitive dreams although the trio are still curious about why, out of the many people around them, they were the ones chosen to have such dreams.

Meanwhile, Hong-joo has long been discomfited by one recurring dream, which shows herself wearing a blue jacket-like field reporter's uniform and lying apparently dead on a grassy terrain during a rainy night. It was the dream which compelled her to leave her job as a field reporter in SBC and to work alongside her mother in their restaurant.

However, Hong-joo intends to return to work after concluding that she can change the future portrayed in their dreams, but her mother is against her plans out of her fear that her dream might actually come true. To convince her mother, Hong-joo brings a fire extinguisher and saves coffee shop attendant Kang Cho-hee (Kim Da-ye) who was bound to be burned to her death in a fire. Jae-chan and Woo-tak, who dreamed about the same incident, works together to keep Hong-joo safe.

On the other hand, the Division 3 Prosecutors' Office (including Inspector Choi) investigates a car accident case involving Cho-hee's older brothers. The younger of these two brothers, Kang Byung-hee, apparently died when the other, Kang Dae-hee (Kang Ki-young), drove the vehicle. The seemingly distressed Dae-hee refused an autopsy to be done to his brother's corpse and requested it to be cremated.

After his younger brother's cremation, Kang Dae-hee goes to Lawyer Lee Yoo-beom and, offering him a big sum of money, reveals to him that he had actually killed his brother Byung-hee so that he can claim his insurance. He had mixed Byung-hee's herbal drink with potassium cyanide and crashed his car to make the scene look like a car accident.

Meanwhile, Jae-chan dreams of himself and Hong-joo watching the latter reporting on TV that a man named Kang Dae-hee was proven guilty of killing both of his younger brother and younger sister for their insurance money and consequently sentenced to life imprisonment. The next day, during a meeting between him and his colleagues, Jae-chan learns at the prosecution office that Dae-hee is already accused of killing his younger brother for the insurance, and that Dae-hee's younger sister (Cho-hee) is still alive. At her work, Hong-joo began covering a serial poisoning case of about 100 cats around Seoul.

To prosecute Dae-hee, Jae-chan's fellow prosecutor Shin Hee-min (Ko Sung-hee) takes the case but her arguments get overruled by Yoo-beom's which claim that Hee-min's evidence are insignificant to charge Dae-hee, who was then acquitted. On the other hand, Jae-chan gets worried after dreaming once again, this time seeing Dae-hee attacking Hong-joo and his sister Cho-hee at a building rooftop. Hong-joo, who was still gathering data about the serial cat poisoning, goes with Woo-tak to a chicken restaurant where she once saw a man feeding cats, not knowing that it was actually Dae-hee.

As the ambulance arrives to rescue Woo-tak, Jae-chan and Inspector Choi arrest Dae-hee, saving Hong-joo and Cho-hee. The murder case was reopened and with Jae-chan taking over it, he gathers all evidences of the crime, which also points Dae-hee as the culprit of the serial cat poisoning. Kang Dae-hee is finally convicted of murder in the re-trial and Jae-chan successfully sought a life sentence for the killer.

After the struggle with Dae-hee, Jae-chan and Hong-joo decide to recompense Woo-tak until his recovery for his efforts to keep Hong-joo safe. Previously, it was Jae-chan who requested Woo-tak to watch over Hong-joo after he saw the two dreams on Dae-hee. Steadily, Woo-tak is having an affection for Hong-joo, although he is keeping his feelings concealed sensing that Hong-joo and Jae-chan are developing feelings for each other. Hong-joo also sees another dream where Jae-chan crosses the street at night, carrying a couples ring for her.

Soon after Woo-tak's recovery, Hong-joo and Woo-tak dream about Do Hak-young (Baek Sung-hyun), the latter's roommate and friend in high school who works as an internet installer. In Hong-joo's dream, Hak-young barges in Woo-tak's house at night and asks for his help in a case he gets involved in. In Woo-tak's, he saw himself being interrogated by Jae-chan because of Hak-young. A worried Hong-joo checks up on Woo-tak, shortly before Hak-young actually arrives in his house.

With the public enraged by Soo-kyung's sudden death, Jae-chan investigates the crime at once and cross-examines Woo-tak to find out more about the suspect Do Hak-young's past. He gradually thinks that Hak-young is actually innocent, though he is still clueless about the geometrical figure on the floor which was impossible for a person to create within a short period of time. The autopsy results also showed that Soo-kyung has a history of otolithiasis, that she died out of cerebral hemorrhage, and that she had no scars on her body except for a wound on her head.

On the other hand, Lawyer Yoo-beom involves himself in the case as the plaintiff for the Yoo family, insisting that Jae-chan is being too time-consuming with the case. Yoo-beom also tries to persuade Hong-joo to make an online article revealing Hak-young's personal information so that she can "help" in finding evidence against Hak-young using social media. Nevertheless, Hong-joo considers Hak-young's personal information irrelevant to the case and refuses to post them in media. With the lack of evidence, Jae-chan sets Hak-young free.

Hong-joo and her mother, Woo-tak, and Seung-won all feel saddened to hear about Jae-chan's forthcoming disaster. Hong-joo also suspects that the change in her dream is attributed to Hak-young's release. In addition, the public is in outrage with the prosecution with Jae-chan being the subject of every criticism about Hak-young's case, especially in social media. When the criticisms seemed to be out of hand, Hong-joo opens a link in one of the comments for an anti-Jae-chan article (유수경 살인 사건 현장에 핏자국을 보니까 떠오르는 사진; Yusugyeong sarin sageon hyeonjange pitjagugeul bonikka tteo-oreuneun sajin; English: The bloodstains at the scene of Yoo Soo-kyung's murder case reminds me of a photo), leading to a picture of a robot vacuum cleaner running over a dog's excrement creating a geometric pattern on the floor similar to the blood pattern in Yoo Soo-kyung's case.

At the same time, Soo-kyung's housekeeper, whom Jae-chan was interrogating as a witness, also mentions of a robot vacuum cleaner which, according to Inspector Choi, was not found among the items inside the victim's residence. Putting the clues together, however, Inspector Choi infers that Soo-kyung could have fainted due to her otolithiasis and lost a lot of blood out of a head injury upon her fall, while the robot vacuum cleaner ran over the pool of blood, created the pattern on the floor, and strayed outside the house (making the inspection team unable to retrieve it).

To prove their hypothesis, Jae-chan traced the item with Inspector Choi and found it in an e-waste disposal facility with the help of Hong-joo (with co-worker Bong Du-hyun) and Woo-tak (with fellow policeman Oh Kyung-han). Yoo Soo-kyung's blood was found in it, attesting their claim and proving Hak-young's innocence. Upon a request from Woo-tak, Hong-joo gives Hak-young a chance to make a public appeal of his innocence to be broadcast in the media.

After shooting Jae-chan, Yoo Man-ho finds Woo-tak and Hak-young and attempts to ram them with his car. As Woo-tak and Hak-young were about to get killed, the police apprehend Yoo Man-ho but finds him unconscious inside his car. Jae-chan is rushed to the hospital for emergency treatment and he fortunately improves from his injury. Man-ho is also confined to the hospital due to his worsening pancreatic cancer. Yoo-beom is also brought in by the prosecution for interrogation for instigating Yoo Man-ho to assassinate Jae-chan, in which Yoo-beom accused the prosecution for fabricating the evidence that it was the robot cleaner who ran over Soo-kyung's blood pool and created the pattern in order to irresponsibly clear Hak-young's name. The prosecutors looking at the interrogation from another room, including Yoo-beom's former colleagues, had begin to realise Yoo-beom's true colours.

Hong-joo receives the engagement ring from the still confined Jae-chan, but along with it is a note which she had given to a childhood acquaintance whose father was killed by the same person who killed hers when she was still a teenager. She realizes that Jae-chan was that childhood acquaintance, whose father Police Chief Officer Jung Il-seung (Jang Hyun-sung) was killed by a runaway soldier who also killed her father Nam Chul-doo (Choi Won-young), a bus driver.

Thirteen years ago, the deaths of Hong-joo's father and Jae-chan's father were given the same funeral, since their deaths happened at the same day and from the same culprit. It was during the funeral when Hong-joo, a.k.a. Bamtori, met Jae-chan. Teenagers Hong-joo and Jae-chan ran into a teary-eyed police officer, who was the culprit's older brother. The policeman, who was also Chief Jung's subordinate, asked for forgiveness but the bereaved teenagers rebuked him. Deeply ashamed of his younger brother's crimes, the policeman ran away and attempted to commit suicide by drowning himself in a lake. Jae-chan decided to save the policeman with Hong-joo's help, but while he was underwater Hong-joo hesitated out of her anger towards the policeman. As Jae-chan and the policeman were about to completely drown, Hong-joo rids herself of all resentment and pulls them out of the water. Because of these bad memories, especially of nearly killing Jae-chan in the lake, Hong-joo hesitates to wear the ring Jae-chan gave her. Feeling sad about it, Hong-joo reveals to Jae-chan what really happened at the lake, telling him that it pains her to see him, the boy she nearly killed.

As Hong-joo attends a book launching ceremony, Jae-chan intends to interrogate Yoo Man-ho for what he had done to him. Accompanied by Prosecutor Shin, Jae-chan suddenly remembers his teenage years with Hong-joo and feels a change of heart. He clarifies, instead, to Man-ho the truth about Yoo Soo-kyung's case.

Meanwhile, Lawyer Yoo-beom receives a call from a new client, professor-novelist Moon Tae-min (Ryu Tae-ho) who has recently finished his launch party for his new book. During this party, his teaching assistant Lee Hwan (Moon Yong-suk) revealed his being abusive to his students and subordinates. Professor Moon then secretly strangled Lee Hwan and pushed him down a derelict elevator shaft. With the crime finished, Professor Moon becomes apprehensive when he notices a child's cap lying nearby on the floor, implying that someone saw him killing his teaching assistant. The victim is already brain-dead in the hospital, can ultimately die within a week, and is a prospective organ donor to seven patients, while the witness is a five-year-old kindergartner.

In line with Professor Moon's case, Hong-joo and Woo-tak both dream of Jae-chan resigning from his job. In Hong-joo's dream, Jae-chan conducts an autopsy and successfully prosecutes Professor Moon, but the seven patients waiting for the transplant perish in return. In Woo-tak's version, Jae-chan agrees with the organ transplant and reveals in court that Professor Moon is the culprit, but with no autopsy done, Professor Moon is acquitted from the murder charge while Lee Hwan's father (Kim Ki-cheon) blames Jae-chan for Professor Moon's release.

Jae-chan begins with the lawsuit against Professor Moon. While Yoo-beom kept on asserting Professor Moon's innocence, Jae-chan interrogates the kindergartner, using childlike language to establish rapport with the child. With the help of senior prosecutor Son Woo-joo (Bae Hae-sun), the credibility of the autopsy results and the possibility of a transplant be done before an autopsy were proven.

At the beach, Jae-chan and Hong-joo wonder if they could still meet the police officer they saved at the lake thirteen years ago. Jae-chan supposes that they could have crossed their paths with him once though they could have not recognized him.

After Professor Moon's case, Lawyer Yoo-beom invites Inspector Choi and Jae-chan's assisting officer Moon Hyang-mi (Park Jin-joo) to work at Yoo-beom's company, the Haekwang Law Firm. Inspector Choi refuses the offer and chooses to stay. Jae-chan, who learns from Hyang-mi about Yoo-beom's offer, tries to convince Inspector Choi not to quit his job.

Meanwhile, Jae-chan receives from his younger brother Seung-won the last will of Dr. Myung Yi-suk, the father of Seung-won's classmate Myung Dae-gu and the supposed culprit of an intravenous drip serial killing case of 11 hospital patients. Years ago, it was Yoo-beom who handled the case when he was still a prosecutor, and the case earned him an award from the Public Prosecutor General. Recently, Myung Yi-suk, who was subsequently convicted and punished with a life sentence, committed suicide inside his prison cell and left a note saying that he was falsely accused of the crime.

On the other hand, Hong-joo is tasked to cover prosecution work for a TV program in SBC titled "Three-Day Experience." At first, she covered Prosecutor Shin in her daily activities. For the night shift, she covered Jae-chan who was interrogating a cellphone thief whose paralytic nine-year-old daughter died when he was in jail a decade ago. The thief, then, gives him a flash drive, which contains files from one of the phones he recently pocketed.

While being rushed with Hong-joo to the hospital, Jae-chan wonders how Inspector Choi managed to find them. Upon reporting back to their works, Jae-chan and Hong-joo learns that the remaining eight patients in the 19 photos were killed after Myung Yi-suk's arrest, further proving the existence of a real culprit, which they infer also as the culprit behind the arson that nearly killed them. Jae-chan and another senior prosecutor Lee Ji-kwang (Min Sung-wook) are instructed to reinvestigate the intravenous drip serial killing case, while Prosecutors Son and Shin are directed to inspect the arson case. With the reopening of the IV drip killings, it is assumed that there is an error in Yoo-beom and Inspector Choi's investigation, but Jae-chan strongly believes in Inspector Choi's innocence.

On the other hand, Yoo-beom began receiving ominous text messages from an unknown source, asking him if he really manipulated the evidences for the IV drip serial killing case. He was also interviewed by Hong-joo who told him that she already knew that something went wrong with the case and that he could be the one to be blamed. Yoo-beom decides to unmask the secret texter by meeting him up at his office late at night. Just as the prosecution and Hong-joo's reporting team found out that it was actually a woman who owned the phone and bought the gasoline used for the arson, the secret texter and the real culprit of the serial killing, Ha Joo-an (Lee Na-ra), revealed herself to Yoo-beom.

Joo-an discloses to Yoo-beom her bitter past which lead her to doing such a heinous crime. She was a bed-ridden patient having Crohn's disease, and she utterly despised her fellow patients who were already being discharged from the hospital. Even though she knew it was extremely evil, she injected her first 11 victims with fatal amounts of Vecaron and, after Myung Yi-suk's arrest, killed in the same manner the remaining eight. She did not even care if she will be punished, but with Yoo-beom prosecuting another person instead of her, she sensed a feeling of hope for the first time. Now that the case is being reinvestigated, she knew the Yoo-beom's fame as a lawyer may be ruined soon, and during the whole conversation, Joo-an was remorseless about the deaths of the 19 innocent people whom she murdered. Completely distraught, Yoo-beom plans to put Hong-joo in a trap so that the secret of the case will only be kept between him and Joo-an.

At the prosecution office, Jae-chan discovers that Inspector Choi was the policeman he and Hong-joo saved from committing suicide in the lake. Inspector Choi was the older brother of the young runaway soldier who murdered Jae-chan and Hong-joo's fathers. When Jae-chan seeks to be reconciled with him, the former policeman quits from his job as an inspector after days of tolerating the suspicions and rumors about him manipulating the evidences in the IV drip killing case. He leaves his resignation letter to Jae-chan, pleading his innocence from the accusations.

While being drugged by Joo-an, Hong-joo spoke as if talking to Jae-chan so that he will find out through dreaming the exact time and place of her impending death. Minutes before, Jae-chan dreams exactly as how the incident would happen and rushes to save Hong-joo, asking back-up from Woo-tak and the rest of the police.

As Woo-tak and the reinforcements arrive first, Yoo-beom decides to kill Joo-an to rid of all suspicions. He took a sleeping pill so that he can pretend that he had been drugged also by Joo-an. Before Joo-an can defend herself, he pushed her off the building just as Woo-tak reached the rooftop. Jae-chan arrives next and immediately resuscitates Hong-joo before the ambulance arrived to rescue her and Yoo-beom.

At the hospital, Yoo-beom wakes up and tells the police detectives his fake story, but he suddenly felt nervous upon learning that Hong-joo also recovered, thanks to Jae-chan's early response. Jae-chan gets furious upon hearing that Yoo-beom had played victim, but Inspector Choi arrives to comfort him and to advise him not to act rashly. Later, Hong-joo is discharged and is placed under witness protection, while the prosecution prepares for the lawsuit against Yoo-beom, who will be defended by his boss, Lawyer Ko Sung-ho (Son Byong-ho). Yoo-beom will be charged by the prosecution of evidence tampering, attempted murder of Hong-joo, and the murder of Ha Joo-an.

As the lawsuit verges to its opening, Woo-tak gets anxious after dreaming the fates of the three witnesses to be summoned to court: Inspector Choi telling his part in the investigation of the IV drip killing case, Hong-joo's statements getting impeached, and finally his own long-hidden secret going to be exposed. The evidence lists were read and reviewed on the first day of the lawsuit, with Jae-chan and senior prosecutor Lee Ji-kwang representing the prosecution. Lawyer Ko disagreed with the statements presented by Inspector Choi, Hong-joo, and Woo-tak and requested to the judges for a subpoena to be imposed on the three. Before the day of the next trial, Hong-joo, Jae-chan, and Woo-tak spend time with each other. While Hong-joo excused herself to answer a call, Jae-chan and Woo-tak revealed to one another that both of them had feelings for Hong-joo and decided to keep their friendship going nevertheless.

On the next trial, cross-examination of the witnesses began with Inspector Choi. As what Woo-tak had dreamt, Inspector Choi admits that he is part of the inspection of the seized items related to the IV drip serial killing case. He told the court that he was with Yoo-beom when he rechecked the seized items and saw three bottles of Vecaron, which were not among the items before. When Lawyer Ko nearly destroys his credibility as witness, Jae-chan won the juries over by emphasizing the fact the Yoo-beom have fabricated evidences to gain fame and a position in Lawyer Ko's law firm. Hong-joo was interrogated next and, as what Woo-tak had dreamt, her statements get impeached since Lawyer Ko insisted that she had been drugged and could have only been hallucinating. To counter the argument, Jae-chan impeaches Yoo-beom's statements since the latter declares that he was also drugged by Joo-an and, thus, should be assumed to be hallucinating also during the incident.

While Hong-joo talks to Woo-tak about the umbrellas and Woo-tak's colorblindness, Inspector Choi informs Jae-chan and Ji-kwang that Yoo-beom plans to escape from Korea after the trial. Later, Woo-tak is being questioned and reveals his color blindness, even though it will cost him his career as a police officer, shocking Jae-chan and everybody in the court. Before Lawyer Ko can impeach his statements, though, he demonstrates that even though he is colorblind, he can describe the umbrellas accurately by their shades and form. By describing the shape of the umbrellas and using Yoo-beom's green necktie and the red lace on Jae-chan's robe as color references, he is able to convince the judges and establish his credibility. He also adds that he has already prepared his resignation letter so that he can testify in the trial.

Lawyer Ko gives up the case and tells Yoo-beom to create his own statements for himself, knowing that they will be defeated in the next and last trial. The prosecution quickly requests a travel ban on Yoo-beom. Devastated, Yoo-beom rebukes Inspector Choi and deliberately rams his car into him in front of Jae-chan. As Yoo-beom is taken away by the police, the dying inspector reveals to the mourning Jae-chan that he also had the ability to see the future through dreams and that he had foreseen his death by Yoo-beom in a dream when he was still a policeman. Jae-chan expresses his respect and thanks to him, apologizing to him for not being able to recognize him when they first met at the prosecution office, for compelling him to work too hard on investigations, and for making him worry when he acted foolishly. Inspector Choi says his last words to Jae-chan before he finally dies. After Inspector Choi's funeral, Yoo-beom finally admits his crimes and is sentenced to life imprisonment.

Days after Yoo-beom's trial, Hong-joo and Jae-chan go to Woo-tak's to provide him books so that Woo-tak can study law and become a lawyer, now that he is unemployed. A year later, pianist and Seung-won's girlfriend Park So-yoon returns to Korea. Together with Hong-joo, Jae-chan, and their friends and colleagues, she attends the wedding party of senior prosecutors Ji-kwang and Son Woo-joo, who had been dating, unknown to their co-workers in the prosecution office. Hong-Joo catches the wedding bouquet thrown by the bride.
