Ikenai Mousou Fudanshi

From Nakama:

As someone who does things like secretly reading BL manga, Satou finds himself imagining "entanglements" with men on a daily basis. However, since he also has a girlfriend, Satou convinces himself that this is a mere hobby, and he himself is not gay. Suddenly, he then finds himself roommates with his perfect, ideal handyman type, a man called Arihara. Imagining more and more indecent things, after a war with himself, Satou eventually comes to accept the romantic feelings in his heart. A BL story about complicated fudashi tendencies, with slightly tortured and realistic characters. *heart* Also, this compilation includes a pure love story of a librarian with glasses and a flashy high school boy!!
