After Rebirth, She Became the System

Just playing a game adapted from a novel, Cheng Xiaodie was inexplicably sucked away into the world of the novel. She, who was supposed to be the heroine, became the system, and the system, which was supposed to be the golden finger of the heroine, became the system of the male protagonist, and the timelines still don't match up... Cheng Xiaodie:...... Okay, let's be systematic, I won't have to worry about food and clothing, and I can still complain without any worries. But, why does she become the heroine as soon as the male protagonist meets the heroine? Could it be that there is a bad contact? Emmm, this is a serious problem!
