Osananajimi Kanojo no Morahara ga Hidoin de Zetsuen Sengen shite Yatta

My childhood friend is also my girlfriend. A dream come true, right? Hell no. She insults me on a daily basis. She grinds my dignity into shreds and it takes a toll on my mental well-being. I can't take it anymore. So I'm left with no choice, I'm going to break up with her. In order to maintain my sanity, it's the only option.
