As someone who was bullied when I was young, I have to say that this is still totally wrong.
I remember Aihara from the first episode, even when he deserved to get the shit beaten out of him for both being a bully and cheating Nagisa, I still think that making him to change sex and rape him was too much, and at the same time I can’t help but to give kudos for that original idea, I’ve seen quite a few hypnosis hentai but no one ever the MC hypnotized the bully to turn him into his bitch, that’s totally new for me, even after seeing Residence and other DATE doujins.
