Kwon, an old friend of trio arrives and is greeted by Ki Bum. They are what he’s studying and is told that everyone is studying for the same civil servant exam.

Kwon meets up with Dong Young and Ki Bum. Dong Young tells him that he heard that he switched to social work. but Kwon switched again to real estate because all he has to do is show clients around here and there. He is super excited to go to the hostel to study. He ends up back at the hostel with police officers and Ki Bum as if he was in trouble. He admits that he got lost and suddenly all the memories of him getting lost came back to the 2 men. Kwon decided to switch to being a police officer. Ki Bum pushes him and takes him for a jog but he gets winded and he asks if he can really make it as a police officer. Finally, they sit down and try to figure out something he can go. He thanks them but leaves for the hostel. While thinking over Kwon, Dong Young gets a call from Gong Myung asking for his notes. Only then does he find out Gong Myung was in the hospital.

Gong Myung tells him that Jung Suk is his brother and Ki Bum asks why he kept it a secret and he tells him that his brother didn’t want anyone finding out. Ki Bum agrees and tells him that it’s unfair that his brother got all the studying genes.
They are sitting in the waiting room when Dong Young comes. He complains about seeing premium trash.

Jung Suk notices Ha Na’s watch and when Gong Myung comes back he asks about it. Gong Myung mentions that it’s his girlfriends and Jung Suk can’t believe it. He reminds him that he should be studying and it makes him pathetic. Gong Myung retorts that he’s certain that he’s never liked anyone and that’s why everyone calls him premium trash. He explains the idea behind it and it cuts Jung Suk hard. He tells him that since he’s premium trash then he should leave and not care about his brother. His brother agrees and Jung Suk leaves in a daze.
Chae Yeon continues thinking about Gong Myung all evening. Finally, she calls him and tells him that she’s going to stop tutoring him. She gives him a poor reason but once she’s hung up Ki Bum gets mad. Dong Young tells him not to tell her, Ki Bum doesn’t know what it would hurt. He tells her that Gong Myung got into a car accident because he was studying while walking.
Chae Yeon is on the roof thinking when Gong Myung calls her. He asks if she’s mad and she admits she heard everything. She blames herself for him getting hurt, but he tells her not to worry and he’s fine. He tells her that he’s studying and she makes sure that he’s ok and agrees to meet with him the following day. Once she hangs up she breaks down crying and apologises to Gong Myung.
Dong Young notices and wonders why she’s crying. He heads downstairs and bumps into Ki Bum. He asks if Chae Yeon was on the terrace because he heard she might be. Dong Young tells him no and ushers her away.
Gong Myung is studying when he notices Ha Na’s watch. He takes a moment to stare at it.
Ha Na is working hard but she keeps getting distracted . Gong Myung ends up texting Ha Na about the watch and promises to take care of it. He asks if she managed to remove the ring and she admits that she hadn’t been able too. He takes a picture and shows her his copy of the ring and tells her that it’s their couple ring. Ha Na gets up and goes to grab a beer. She smiles at the picture. When she backs out of her messages she notices Jung Suk contacted her.
Jung Suk is irritated that she didn’t contact him again and she texts him that she hasn’t heard his confession and to not contact her.
The next morning Jung Suk goes to fly his drone but Gong Myung’s words run through his head. He’s determined to not care what people think about him but once he lands his drone he thinks of Ha Na.

He wonders what he did to cause her to go cold and then he remembers everything. He suddenly is determined to win her back.
Ha Na is ready to start her day like nothing happened however Jung Suk is waiting for her.
