I Personally don't get the anger at siwon??

Instead outright telling siwon the truth when they first set eyes on villain, kings tried to take care of it himself. Then he let the old friend act continue so ofc siwon acts friendly. Jinha acts from siwons eyes suddenly angry when villain never ever provoked him. Of course siwon would think jinha is just being jealous since he turns to violence when he's jealous like with donghyun. Y'all are honestly so illogical. Siwon ofc feels like villain is getting targeted because of him so of course he wants to make up for it by being helpful to villain. Plus they have "so much in common" siwon is glad to have a new friend. Everyone always gets angry at the uke in every single manhwa/manga I read. In this one especially siwon should not be blamed. I'm not saying jinha is to blame but it's understandable miscommunication and frustrating nevertheless
