Why would Nanjoo lie to the twink about being sick to not attend his birthday and send him a gift instead if he's that important to him and going through this shit to protect him? He also got mad thinking Mokyeon has met with the twink, so is Nanjoo already developing feelings for Mokyeon or maybe confused about his feelings towards the two?
This was a misunderstanding but imagine what would happen in a more serious situation! Chae-heon is a red flag and has always been since the beginning of this Manhwa and I thought Jeong-yoon is stupid but turned out he's an other freak in this story, I'm not complaining they much each other.
That's why these kind of personalities are only cute in fiction!
