I think he suffers well enough, and part of why I think that is because he redeemed himself and we can see how much mc means to him, and also because mc suffered during that time as well, it'd have been nice if mc could've moved on and didn't suffer like ml, but that's just his personality, and I like that it's sort of realistic about that part, what's important to me is that he stood up for himself and now their relationship is more equal.
heard he remained selfish all throughout the story....he just changed how he treats the brown hair cause he fell for him. how true is this? (if you have read the novel)
i really don't mind that they get together since i ve seen the spoilers but would it hurt for them to give the readers' satisfaction by making sungbin suffer more...? lmao. i don't think he's the type to ever learn without experiencing it himself
