The joke isn't that she's innocent, it's that she's competent at everything except understanding why her boyfriend is horrified when she pragmatically suggests they have sex in increasingly public places. Every episode commits fully to the premise without breaking character or winking at the audience. If you hate sexual humor, this show will repel you instantly; if you're built for it, the consistency and timing make it funnier than comedies five times its budget.
Haruka never expected his confession to the perfect class representative to actually work. Akiho Kousaka is beautiful, brilliant, and impossibly serious about everything she does. So when she agrees to date him, Haruka thinks he's won the lottery. What he doesn't realize is that Akiho's relentless dedication to self-improvement extends to romance itself. She approaches their relationship like any other challenge: with research, determination, and a complete lack of awareness about appropriate teenage couple behavior. Her well-intentioned attempts at intimacy are wildly miscalibrated, swinging between charmingly awkward and genuinely alarming. Haruka finds himself constantly blindsided by her straightforward suggestions and deadpan declarations. The comedy comes from watching an ordinary guy navigate dating someone who treats physical affection like a homework assignment while genuinely caring about him. It's a high school romance that trades emotional sincerity for rapid-fire absurdist humor, where the real obstacle isn't winning her heart but surviving her interpretation of what boyfriends and girlfriends are supposed to do.
