Okay, I hate mangas like this for two reasons.. 1. "HIS MAJESTY" is seen as the villain throughout the whole story(which him and that purple haired girl can rot in the furthest corner of H3LL for all I care), however since things will change when she goes back in time, she someone how forgives the things he did to her in her past life and falls in love with him. 2. The revenge the MC gives out is shit compared to what the people she's getting "revenge" on is doing to her.
Edit: This is just my rant from only reading the first chapter.
