When I was reincarnated, I found myself in a role I despised, playing the promiscuous protagonist in a netori game. To make matters worse, the story was already in the middle, and my step-sister, the heroine, was being threatened and almost turned into a submissive slave. This is absolutely wrong. I erased all the data that was being used to blackmail her and set the heroine free from slavery. I decided to leave home, but for some reason, the heroine stopped me and started showing affection towards me. Gradually, our love deepened. When I go to school, I become the target of the disciplinary committee chairman. I'm also being seduced by bitches and is forced into intimate situations... I want to live a pure and righteous life, eradicating my promiscuous past! It seems being the promiscuous protagonist is not going as smoothly as I thought.
