>yfw your crush steals your (fake) girlfriend's first kiss and instead of being shocked she starts to enjoy herself
I didn't expect it to go double the NTR, but I guess It's better then going harem again, right?
The impression that under the genki facade senpai will be the annoying character, seems to come true. She was only teasing about the kiss, since it was CPR and it seems she'll only use her charms to make the MC to do shit for her and tease him just enough to keep his hopes up, but never actually go there.
The sister's conviction will probably be as shallow as her fetish, so that seems like a dead end.
he doesn't seem to like senpai anymore.
Oh on the contrary he will stick to senpai for as long as the manga will run and only change his mind when it will be about to end.
