Blondie is not an asshole. He's been nothing but nice to the mc. He like MC since childhood. He came looking for him and tried to win his heart but he has not done anything at all to hurt anybody in the entire manhwa at all. Y'all just call anybody other than the MC or ML an asshole for the heck of it,coz your brain didn't develop after 5th grade.
As for what's happening with he silver hair guy, blondie is a little oblivious to his feelings but that doesn't make him an asshole by default. Ooffffff get some comprehension classes coz you clearly don't get anything
Mate he knew mc was going out with ml and also that mc didn't like him like that SINCE HE FUCKING TOLD HIM and nonetheless he STILL tried to kiss mc not only hurting ml ( and yes you don't have to punch someone to hurt him) but also going REALLY FUCKING CLOSE to harassment. Also you don't need to be disrespectful to get your point across, and yes blondie might not have realised that silver hair has feelings for him but he definitely still toyed with him. You don't flirt with your friend , you don't try to get him to sit on you while only wearing a towel, you don't basically force him to live in the same apartment with you cause "i like having you around" and you can only be SO much unaware so even if he didn't know the other is in love with him he knows there's still some interest even if he might think it's just sexual from the other party but still pretends there's nothing. And we fucking need to make this clear apparently BEING NICE/ DOING NICE THINGS FOR SOMEONE BECAUSE YOU WANT TO GAIN SOMETHING FROM IT DOESN'T FUCKING MAKE YOU A NICE PERSON IT MAKES YOU A FUCKING ASSHOLE AND YES BLONDIE WAS DOING ALL THAT SHIT JUST BECAUSE HE THOUGHT THAT BY DOING SO HE WOULD GET MC TO DATE HIM SO YES HE IS AN ASSHOLE.
So i found out that silver hair at the end of this season (i think max 3 chapters from now if not the next) leaves that asshole of a blondie and gets on a plane (from what I understood). After seeing Ines (i love her so much omg) winking at him I think that she offered him a job and he accepted after hearing Hajin talking cause he's tired of the situation, now THIS IS ALL MY HYPOTHESIS CAUSE I JUST FOUND SNIPPETS OF THAT CHAPTER ON IG. I'm just so happy that he finally leaves that bitch and I hope that the author actually makes the french dude regret everything and gives him an actual redemption arc instead of having him apologise once and the cutie pie silver hair just take him back, or that the bean doesn't forgive him and just moves on with someone worthy of him ╥﹏╥ ╥﹏╥
