you and yeonjun are roommates but never talk to each other. yeonjun was energetic and extroverted but he always brought his ex-girlfriend, jiwoo, to the apartment and do stuff with her. meanwhile you minded your own business, you were quiet and introverted but loved watching Kdramas and listening to Kpop music...

you never really spoke or looked at yeonjun...you guys would look at each other for at least a few seconds and then do your own stuff. yeonjun was always working too while you were in university.

one night you were watching a Kdrama when you heard noise coming from his room.
