Boku no Kanojo ga Majimesugiru Sho-bitch na Ken

Haruka Shinozaki confesses to class representative Akiho Kousaka, the smart, athletic model student he has admired for years, and is delighted when she agrees to date him. The surprise comes afterward: Akiho has never been in a relationship, so she prepares for romance with the same extreme seriousness she applies to everything else, studying what she thinks will please her boyfriend and delivering wildly suggestive ideas with a perfectly straight face. Haruka keeps trying to explain that love does not need this much research, but their equally eccentric friends only make matters worse. His first relationship becomes a chain of misunderstandings and innuendo as both slowly learn what they actually want from each other.
