Thank God some one said it. I see comments like this all the time. Asma, hun, its cuz the characters in this webtoon have dimension. And real world common sense. Are you gonna stick ur dick in a psycho hole, prolly not fam. Not saying that other manga and webtoons are bad, cuz they're not, but this one has characters that feel different and have different values. Like Bananan said Yohan isn't some horny teen like in books and tv were guys just wanna shove their weenie in every hole they see (even swiss cheese) , I dont even think he was gay to begin with, so he rejects byung.
Also if it seems like I'm being nasty I'm not. I just saw this and was like " I will also participate in this convo"(⌒▽⌒)
I know u all hate the brother but I'm wondering why did the seme rejected him ,, I mean in all yaoi the seme will accept the uke and love him a lot without any real reason or a convensint character in the uke
