Comprehensive Comic: Improper Labor and Management

What should I do if I travel through the comic book world and become the licking boyfriend of a bunch of girls? Of course, that would be a comeback! Miura Yuko: What should I do so that you can treat me like you treat them! Gui Yanye: It's okay, Mu will be very gentle. Busujima Saeko: I'm so lucky to share the same friendship with you! Hiratsuka Shizuka: You guy, take the responsibility of a man for me! I thought it was just a comprehensive comic, but who knew that there are not only ghouls and monsters here, but also mermaids who have lived for hundreds of millions of years?! Muromi: Nay! Mu, play with me! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
