The episode starts with young Seung Tak boating with his father happily on a summer day. Seung Tak removes his life jacket telling him that it is hot. His father warns him to put it back. Seung Tak puts one hand in and sees something in the water and while trying to see what it is, he falls into the water. His father removes his life jacket and jumps into the water. He saves Seung Tak and puts his life jacket on Seung Tak. In the end, both float in the water unconscious. As soon as they arrive hospital, Seung Tak’s father is pronounced dead and Seung Tak is in serious condition.
In the present, Cha is pushed out of Seung Tak’s body in the OP room. Tes comes but it is too late. They see the ghost of the patient disappearing. Seung Tak is so scared that he drops everything and runs out of the OP room.
The next day, ADD Han, Chief Ban and the other chiefs discuss the cause of death. Chief Ban says it was too late when the patient arrived. Still, Seung Tak tried what he could so they say it can’t be blamed on him. ADD Han says one would think they all were in this together and he will look into whether it was medical malpractice or not. And he asks Chief Bam why he is not in the op room as Cha’s surgery was scheduled for today.
Jae Won explains to Se Jin that Cha’s operation is cancelled. Se Jin gets furious and asks how can they cancel the operation and tries to call Seung Tak. Jae Won says that Seung Tak is the problem.
Cha goes to the funeral of the deceased and remembers how Seung Tak ran from OP without even looking back.
In the hospital, Cha sits on the stairs worried. Tes comes to him and says that they should have considered his warning. Cha explains how he flung out of Seung Tak’s body in the OP room. Tes says the patient would have died even though Cha stayed in his body. He says he shouldn’t have decided to operate on him. Cha says it was Seung Tak’s decision and says he looked into Seung Tak’s eyes and couldn’t turn him down. Tes says Seung Tak must have had the same eyes which Cha had years back. Cha says Seung Tak won’t be able to come back and blames himself and says he shouldn’t have gone into his body until the end. Tes says if he knows that it was his fault, he should take responsibility instead of just sitting there and he leaves after saying that both the big one and the little one are clueless.
Cha goes to his department and sees that Jae Won isn’t able to reach Seung Tak. Two other doctors bad-mouth him and to Cha’s surprise, Seon Ho takes Seung Tak’s side.
Cha then goes to Soo Jung and sees that Seung Tak isn’t picking up her call as well. One of her department seniors says that he knew Seung Tak would cause trouble one day and says he was too desperate. To everyone’s surprise, Soo Jung talks back and asks shouldn’t doctors be desperate to save the patients.
Cha finally goes to Seung Tak’s mother’s office and listens to her secretary telling how they couldn’t find Seung Tak anywhere. ADD Han enters the office and asks her if Seung Tak didn’t go home. He then says Seung Tak is stronger than they give him credit for and says he will return soon. He says he will take care of the operation so she doesn’t have to worry about it. Seung Tak’s mother asks ADD Han if he remembers how Seung Tak’s father died while saving Seung Tak and asks him if he remembers the odd condition he developed after that incident and says Seung Tak had to go through a lot back then and she is worried now that he may slip away like before and cries. ADD Han asks then why did she make him a doctor. He says they should have backed up when they had the chance to leave.
In Se Jin’s office, she thinks about how Jae Won said Seung Tak should be the one to perform Cha’s surgery and says how Seung Tak became competent after performing surgery on Cha.
ADD Han gets a report on the operation and learns how they can’t blame Seung Tak. He is positive that Seung Tak walked out on his own and is never coming back.
ADD Han stands near a window in his office and says it is giving him chills thinking that Cha would be there in his office. Cha is sitting on the sofa behind him and asks if he can feel his presence now and asks him to jump out of the window before he could push him. He asks if Han is happy about kicking out his cousin. ADD Han says it was Cha who ruined Seung Tak now and asks if he is feeling better to perform those surgeries. Cha says he is devastated and says he didn’t know Seung Tak had such a tragic past and says he is worried that Seung Tak might get weaker now. ADD Han chuckles at the fact that he is taking alone. Cha then says ADD Han doesn’t know Seung Tak as he does. He says he will make Seung Tak come back.
Se Jin goes to Chief Ban and asks if he wants to let Seung Tak perform Cha’s surgery. Chief Ban says he is the best resident they have and says he has seen him perform surgeries and at first they all thought that he was possessed by a spirit. He then convinces Se Jin to wait longer for Seung Tak but Se Jin is desperate and says she will ask someone else to do the surgery if Seung Tak didn’t come back soon.
Soo Jung goes to Se Jin’s office and sees Cha’s body is alone there and asks if Cha is there and asks him to give her a sign if he was there. But Cha’s soul isn’t there.

Soo Jung is surprised to know that Se Jin knows her and asks if she ate yet. They go to a place to sit down and eat. Se Jin asks if she could contact Seung Tak. Soo Jung says no. She says she didn’t know what Se jin liked so bought something easy to pack. Se Jin asks if she has a tag saying “feed me” and says Seung Tak usually brings her warm soup and rice. Soo Jung is jealous and asks if he did that and mummers he never did something like that for her. Se Jin smiles and says if she is taking Seung Tak’s place now to feed her. Soo Jung says she can’t do much but felt wrong doing nothing so came with food even though she can’t replace him completely. Se Jin smiles and says Seung Tak has a good friend and says she will be strong and asks her not to worry about her instead asks to worry about Seung Tak. They then eat.

ADD Han says An should come back and should perform surgery on Cha. He also says that there was a table death recently and other doctors said it can’t be blamed on the doctor as he was desperate to save the patient. An is scared that Cha might be listening but ADD Han says even if he is listening he can do nothing as Seung Tak is not there.

Soo Jung suddenly confesses and asks if he knew she has a crush on him and says her grandpa would be proud to see him. Seung Tak is shocked and confused and asks why she is talking about her grandpa as he never met him. Soo Jung says her grandpa died 20 years ago and while doing so, he saved a kid and it is not a good sight to see that kid act like this. Seung Tak doesn’t really get that and tries to leave. Soo Jung says Cha’s surgery is postponed and he must be waiting for him and so is Se Jin.
But Seung Tak is determined not to go back.

Seung Tak goes to meet his mom with a big and cosy smile and tries to tell her that he is quitting but his mom dodges to hear that from him. After a while, his mom says this reminds her of the day when he was around ten and came downstairs with a big smile and said “Mom, I am hungry”, “This is delicious, make it often”. She says he pretended as if nothing happened and smiled a lot to make her happy and started acting like a kid from a rich family.

Tes comes and says Cha should have comforted him first. Cha asks him why he helped him 12 years ago when Cha was an intern. Tes says he had the same eyes Seung Tak had.
