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 was the epitome of manliness until he found out that he has powers which really isn't very manly at all because he has the power of... bubbles.  Yes, he has bubble power!!! Yongguk: Damn you author!!! (◣◢)┌∩┐

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
