Hero of the End: Is the Love System Fake?

Evil spirits invade and the end comes. When human beings desperately resisted, the entire army was annihilated due to backstabbing by the surrendering faction. Qi Shaojun was selected to become a guinea pig for the demonic human experiment. On the verge of death, Qi Shaojun suddenly sat in the classroom and became the only boy in the girls' school. "Ding! Your love development system has been activated!" The system beep sounded in my ears. But something is wrong. Those beautiful girls who throw themselves into their arms are always inconsistent with their words and deeds. The information given by the system is not entirely correct either. This world doesn't seem to work as they say. Is it a mixture of truth and falsehood, or is it all made up of lies?
