Well, it was going to happen sooner or later I mean. A relationship just based on sex with no real attraction isn't going to last. She doesn't like him, even after all this I still believe the one she actually truly likes is Kei. Which is why she was always harsh with Yo, insulting him, sometimes even looking disgusted by him, even though she still continued having the relationship. Ain't no way this was going to end any other way.
i don't want to be horny anymore, i just want to be happy - yo
Haha so true lol
Christ. He broke through. Thank God.
Now... Here comes the hard part.
That probably was the hard part imo. Kei will forgive him. The one who truly loses out in this situation is Mitani. As I thought, she'll have nobody now, and she used herself on someone she didn't even like just to spite Kei but in doing so she lost herself and messed herself up. Only to be rejected by the guy she probably perceived to be beneath her.
