Why yall being like 'kayden is a dad' like no. That's big brother behavior right here. Teasing Jiwoo but being secretly super proud of him ? Acting all high and mighty but will throw hands with anyone touching him ? Letting Jiwoo fight his battles but always being here to know when to intervene ? That's hot big brother behavior

character development really made this man 10000x hotter

Honestly in my books, most of the times it's not even actual character development.
The asshole seme just suddenly realizes that he can't have what he wants (the uke) if he doesn't behave differently so he starts to be nicer. But out of completely selfish reasons.
I'm glad that this guy here became a better person because he truly felt bad about the way he behaved, and not just because he figured it was the only way to get his love interest to like him.
I was so sure the manga would end after he was accepted in art school,, im so happy it didn't, the struggle he faces is so real.. Even tho im not an art student nor am i as smart (tho i am a former "gifted" child) i find myself relating so much to him and what he's going through. For example the moment he realize he has so hobby,... i felt that, having depression and no friends i just don't have the energy to do anything most of the time, and even if it's not for the same reasons it's refreshing to see my own struggle represented since i often can't relate to any character in medias
