Goo Jawook decided to pursue Yungyeom, regardless. While overseeing the project at that VIP lounge, the boss lady (the one invited him to that lounge) revealed to him about Yungyeom's dating past. So Yungyeom started to visit this lounge when he was about 20. He dated people, but it wasn't long lasting. Until one day, there was one guy whom he dated for a long period of time. Yungyeom's father suggested/hassled him to get married( to a woman). Perhaps they didn't like him dating a man. After he told the boyfriend this, the bf became insane and eventually set himself on fire...and died. After that Yungyeom, decided to never date to avoid emotional tragedies as such.
Jawook, after knowing Yungyeom's past, understood why Yungyeom always put a distance between them. He realized that it wasn't because he "wasn't an M" that caused the break up, but because Yungyeom didn't want tragic history to repeat itself. Jawook went to Yungyeom's apartment and rang the bell, but met with no response. So he called him on the phone, which he eventually picked up but said nothing. Jawook went ahead and said he wanted them to have a talk and that he'll meet up with him in the room at that VIP lounge. It's a room where people hookup.
Yungyeom moped around and didn't know what to do until he got a call from Yuta, the idol that he manages. The called said that Jawook got attacked by someone at the VIP lounge. Yungyeom, snapped out of his depressive mood and went to look for Ja Wook. He actually does care about Jawook deeply. When he got there and had the manager opened that room, they found Jawook struggling on top of the guy who tried to rape him. The guy got dragged out by security.
So they recconnected and talked. At that time, Jawook decided to officially end the DS contract with Yungyeom, he wanted them to start dating instead. Yungyeom fell on his knees and cried miserably, he still wants that DS relationship. They basically got in a real relationship and "made up" a lot. It's really cute-Yungyeom is totally in love with Ja Wook. They learned more about each other. Although their DS contracted ended, Yungyeom still finds every chance he could to include DS style in their intimate sessions.
The story also went on developing the second couple, Yuta (the idol) and Lee soo eon (Yungyeom's half brother and also worked as supervisor of Yuta)
