I feel like in the comments half of the people are defending Kunhiko and half are hating on him. I don't want to get too caught up in this but really, the we have to admit that he is selfish - he disregards his friends feelings, puts him in a situation where others think he's homosexual, interrupts his chances with a girl but has no qualms having girls to himself, takes advantage of him, and cheats on his girlfriend consistently. Some people are saying he's not a bad person, which he might not be, he's just bad boyfriends material. And I agree that his actions might have some underlying motive/ meaning and there is a lot of opportunity for character development that I hope we get to see.

Literally this is a case of as long as he ends up “romantically” involved with our main male character everything is overlooked. He’s literally trash of person and just a narcissist. There’s actually no redeeming qualitIes to him as you’ve laid out and as is presented in the manga. Yet he’s attractive and he’s potentially “gay for love” and that’s all that matters. It is sad that in reality attractive people can get away with anything even murder in the court of popular opinion.

Oh man, I hate seeing Chanbit sleep with other people. I'm only sticking it out in the hopes that Baekyung gets everything he has ever wanted! All I know is, I definitely could never re-read, because I can't put myself through this heartache again

On that I agree and would read a whole ass manga about therapy, lol.
He is absolutely being victimized by that sadistic bastard, no doubt, however this doesn't absolve his cowardice. He takes and takes and takes from Baekyung and gives nothing back-- ive been on both ends (taker /giver) and it's frustrating but that's on the author.
I just feel sorry for B: he's the one who is getting hurt the most and that's unacceptable to me.

Honestly the Uncle is being a bit of a dick. The red headed boy is so generous and caring, yet I feel like he's totally being taken for granted. I never minded his character even with his personality flaws - lately it seems like the red head is the only one trying to improve himself for the sake of the relationship. I don't like feeling like Uncle will toss him aside at any moment, becasue that boy is naively in love and putting in his best effort
It seemed like he liked his Uncle... even went out of his way to fulfil his dying request and remembered the conversations they had, so why did he do that to his Uncle's kid?
