My Sadistic Boyfriend Vol. 3

Chiaki and the unofficial school prince Katsuho are roommates - as well as boyfriend and girlfriend. On the surface, Katsuho is by all appearances a dazzling prince. However, when alone with Chiaki, the prince becomes a sadist with a perverted streak!
Chiaki is plagued with self-doubt after coming to realize just how much she doesn't know about Katsuho. This tender school love turns a little more serious in volume 3!
