I don't agree with seme being "trash", he just enjoys free sex life, also he doesn't make those random ukes fall in love and ditch them as some of you suggest lmao. It's pretty clear he targets ukes with a similar mindset of "having fun". And he's definitely not cheating wtf they weren't in a relationship in the situation you're talking about. And after they got together seme never cheated and I'm pretty sure he won't in the characters' future, cus look at him, he's fully dedicated to his boyfriend. That manga is suuuper cute
Okay, I want to read it as I see it's finished, but will there be side stories? I don't wanna spoiler myself so I'm not gonna check the last chapter by myself
