The villain forces me to commit suicide every day

Introduction: (The first book for a newcomer, with many flaws, please be considerate. It doesn’t have an outline yet, but I will insist on finishing it.???) Qin Yao was forced to come to the world in the book and complete the tasks given by the system every day. On this day, he must complete the suicide mission and kill the male protagonist Qin Shijin, waiting for his transformation and return. I wonder how he will treat his "brother" when he returns. (The characters in the novel may say to themselves, don’t give up on us.)
