Comprehensive Manga: It's Weird to Pass the Level with Mai-Senpai

Traveling through the comic book world, Wu Geng Liuli is my sister, and classmate Irene is my neighbor. Suddenly I received a small note from Mai-senpai. I thought it was a love letter of confession, but unexpectedly it turned out to be a strange beginning. Welcome to the world of Kaitan, please abide by the following rules. 1. Students should be pure and friendly with each other, and please maintain proper relationships with the opposite sex. Wait, isn't this the boys' dormitory? The roommate who suddenly appeared made Lu Chen a little crazy. "Please, ladies, could you please change to a longer skirt?" "Wash your own socks. Can you not tuck them into my bed?" "Stop rubbing, stop rubbing, he has already stood up!" On the one hand, there were rules that could lead to death upon touching them, and on the other hand, there were girls who were trying different tricks to seduce him. Lu Chen felt like he had a headache! The must-write characters in the later stage are Yukinoshita Yukino, Kotori Yurikka, Kasuga Nokaku, Tokisaki Kurumi, Hoshino Ai...
