Lol sorry but... What????
He's supposed to be in his late 20's yet acts and think like teenager, can't figure out his own feelings and leads on THE good guy rather than communicate.
He was absolutely aware of Jaemin's vices yet kept on worshipping and running back to him for no reason.
Being the eldest sibling of a poor and irresponsible household as he is, you'd expect him to be mature and think things through, yet all he does is cry over the situation he stuck himself in and reject the people who genuinely care for him.
He literally ruined 80 chapters and 10 years of two other men's lives (even though one of them is the final boss of pieces of shit) when he could just have been true to himself, looked at them straight in the eyes and said "ok dudes, fuck this shit I'm out".
The dude is a walking paradox, wth are you talking about? Unless you're 12 how exactly do you approve of him?
istg im going to punch everyone that hates daon !!! YOU GUYS DIDN’T GET THE STORY AT ALL !! the true villain was jaemin, that manipulative ass. and try to understand Daon’s situation—he lives in poverty, his parents r useless, he’s the eldest sibling, he took help from jaemin who he thought was kind, Daon is the victim here.
