I thought the same and i'm also still very confused but then i started to reflect on their previous actions and i think he can't go past the fact that he might be gay or bi and for that he is angry to our uke, but also he was and still is very obsessed with him so because of that i think we can't determine his real feelings for the uke yet.
So, he "IS" have feelings for uke but because of the obsession he has, which is came by years, he can't realize his feelings?
Mmm.. it's something like that, i guess. Maybe? Ugh, idk. Everything is confusing now, the chapters need to keep coming so we can understand what's happening.
Wait what? So ukes ex seme was (or is) actually liking him? I'm confused....
