From mangaupdates:
In order to lose my family's debt (4 billion), I decided to go to a girls' school by dressing as a woman, as per the order of "a pervert who loves romantic comedy and has too much power". School life is full of confusion, but fortunately, in the midst of misfortune, all the members of the student council are "men" who go to girls' schools in the same circumstances. Can you win a peaceful school life despite the perverted old man who wants romantic comedy troubles?
