[GL] Cinderella was bullied because of me

I never believed in second chances or past lives but just as I thought that I died I opened my eyes and found myself in a strange room. I read a lot of isekai in the past and I thought that I had woken up in a book I had read but years went by and I didn't recognize any names. Therefore I just focused on my new life and did whatever I wanted. But it turned out I wasn't in some kind of new world.

I should have seen the signs before. It was obvious just by their names. As soon as I got into High School I ran into Cinderella or at least this world's version of Cinderella. And the evil witch was none other than my childhood best friend. Cinderella may be annoying, she didn't deserve to be bullied by Aspen but when I confronted her about it, it turned out she wasn't bullying Cinderella because of the prince of the school but because of me. How did I get into the equation? Why was this because of me?
