[Comprehensive] Fatal Kiss

* (To be determined)* The gift my mother left me became the beginning of my fall. I used my kiss to get rid of the bad boy who had been bullying me; I kissed my sister secretly while she was unconscious; I was "tricked" by my legal guardian into selling myself for ethereal rewards. ... Before these things happened, I was just an ignorant girl who had never even had her first love. —————— 1. Evil fall. The protagonist is an atypical Sakura girl. 2. Sexual fluidity. There is incest. Concept: Isn't the setting that kissing is a weapon too geeky?
