Kobayashi ga Kawai Sugite Tsurai!!

The Kobayashi twins, Megumu and Mitsuru, were named after historical figures, with only Megumu developing an interest in history. To avoid extra classes threatening his weekend, Mitsuru persuades his sister to exchange clothes so he can pass exams by pretending to be her. Megumu struggles to navigate Mitsuru’s all-boys high school, where academic knowledge alone isn't enough. Meanwhile, Mitsuru discovers that living as a girl in a girls’ school is more challenging than anticipated.
