Activate the Love System and Conquer Your Sister, Best Friend, and Teacher

Li Bei was ordered by his sister to take care of her drunken best friend, but he was used as a pillow to pester her all night long. I thought that everything would be fine if I ran away, but unexpectedly the next day in the sophomore professional class, the legendary and unrivaled female professor Bingshan walked onto the podium in high heels. Facing her cold gaze, Li Bei activated the [Love Emotion Critical Strike System]. In order to become stronger, he could only be a "sixth child": "Professor Lin, you don't want the whole school to know about holding me and calling me brother last night, right?" Seeing the aloof sister being forced to have red eyes and tears of grievance, an extreme pull from "pretending to be unfamiliar" to "two-way sinking" officially kicked off.
