Jongup got along really well with his seatmate in the office named Himchan who already has a boyfriend named Yongguk. People warned Jongup about Himchan's  previous playboy reputation before getting into a relationship with Yongguk. People also couldn't help but notice that Yongguk was being nice to him almost as much as he was being nice to his boyfriend. Jongup ignored what people tell him and denied his own feelings. However, he might not be the only one feeling something.

From Jongup's perspective, Himchan seems to be everybody's boyfriend.  Why does he think of this? Because every single one of Himchan's boyfriends was related to Jongup somehow whether his cousin, his classmate, his friend, or even his teacher.  Then what happens when Himchan shows a hint of interest towards Jongup?    

When everybody was against Himchan, Jongup always sided with Himchan.  When Himchan told everybody that he liked Sunhwa and would try to get her to be his girlfriend, everybody told him to go for it, but Jongup never said anything.  When Himchan finally gets into a relationship with Sunhwa, Jongup finally decides to confess to Himchan and then what happens after that?

Yongguk suggested to young brother, Zelo that Jongup (someone he never met before but had heard a lot from Zelo) could come over to their house and use their exercise equipment.  One afternoon, Yongguk came home to find a topless stranger with defined arm muscles and washboard abs at the exercise area in the house.    

Jongup wondered why Daehyun liked to use him as a pillow when his body is all hard and muscles.  Daehyun gave him an aswer when Jongup finally got the courage to question about this.

Himchan has a prince syndrome who would only classify you as a friend if you have the same high status as he has and if you're not, then you're classifie
