the mc had a crush on a classmate but never confessed. now he moved into a new house and the classmate lives there too. The other two tenants are dating. One of 'em looks like a giant bear and the other one is a high school teacher who's rude to anyone but his lover.
edit for more details: in the a recent chap they made out after mc spotted the two other tenants fcking, but i think the next day the mc tried to act normally??! the mc is a hairstylist btw.
he's a psychopath and the manga did a pretty good job of painting him crazy and scary. I don't see how this is romantic. The girl is held captive and looks scared af lmao. There should be a psychological tag.
