My bully is my lover, sicae, new horizon, realm invader, projekt passion, ripples, TOXICity are a couple I've played so far and I loved them. They're all worth checking out
I've been hedging on My Bully is my Lover for a while now, just because I'm not sure the theme would sit well with me (victim of bullying, myself).
Sorry to hear that, the depiction isn't quite as intense as real bullying is, it's mainly just a girl being rude to you.
And the main story doesn't revolve around that either, it's just the plot between the main character and one of the girls.
