My Girlfriend is Shobitch

僕の彼女がマジメ過ぎるしょびっちな件

Haruka Shinozaki, a shy second-year high school student, confesses to class representative Akiho Kosaka and is stunned when she accepts. Akiho approaches the relationship with the same rigid diligence she brings to everything else, researching dating through textbooks and misinterpreting physical intimacy as a duty to perform. Between Haruka's flustered reactions and interference from his clingy sister Kanata and their eccentric classmates, the couple's attempts at a normal relationship never quite go to plan.
