It's been kinda hinted on that the friend likes bum but didn't do any advances cuz he didn't know hyuk likes guys(though yeonwoo is the first guy he liked), friend just kinda felt he lost his chance to bum and is trying so hard to get between them
I’m not sure the friend is actually interest in MC. Like it’s been chpts of tension and ML being jealous but so far friend hasn’t shown any romantic feelings towards MC. Could be jealousy over his friend being taken away? Could be I’m delusion? Who’s to say except the author lol.
