I understand that he had a rough upbringing
And that he has always waited for his soul mate
But he needs to chill out. Just because he us certain Hayoung is the one for him
Doesn't mean Hayoung feels that way about him (yet)
And certainly marking him without his consent and being possessive and manipulative isn't the way to go about convincing Hayoung to become his mate

Are people seriously hating on Chunwoo sunbae? For real?
The man has a fuck buddy who happens to also be his closest friend. And all this existed before he even knew this new kid.
He became comfortable and close with this new kid, but the second the kid found out he's gay, what did he do?
He ran. He avoided Chunwoo very obviously. He ghosted him. Couldn't even make eye contact or be civil. What exactly are you people expecting from Chunwoo?
The kid couldn't even look him in the face and apologise properly.
If Chunwoo doesn't want to accept a half assed apology from someone whom he thinks is a homophobe (because the kid didn't give him any reason to think otherwise), then yeah, he's well within his rights to.
So what should the kid do? Keep apologising. Because that's what you do if you really want someone in your life. And if he can't do that, and if Chunwoo still doesn't accept, then fine.
Some relationships just don't last and that's alright. But when people are hurt you have to give them a little leeway and time to get over it. If they don't you're free to move on.

I think those people don't realize the comfort in sleeping with someone familiar and close.
Even if it isn't the kind of relationship Chunwoo wants, what he has with Taesoo(?) is still better than being alone, or being with random strangers.
Also to say that Chunwoo "doesn't take control " is completely ignoring the fact that he actually is in control and sleeps with his friend of his own volition.
He isn't being used or exploited. It's mutual.
3 MONTHS without AHJUICY (and Euijoon)?
But then who will quench my unbearable thirst???
