If they find out, it's over! Impersonating my twin brother at an all-boys school!
About
Sora, the brilliant and free-spirited twin brother, suddenly disappeared one day.
The family won't discuss the details, and the only word sent to the all-boys boarding school he attends is a notice of leave of absence.
Repeatedly begged by her desperate parents, the younger sister decides to attend the academy in her brother's place.
Cutting her hair and changing her clothes, she used her identical appearance to step into Aosei Academy.
It's been a week since then. She has been impersonating her brother, living a dorm life surrounded by boys.
Sora's best friend, the Student Council President, a caring senior, and a quiet junior. Interactions with these unique boys are a series of unexpected events...?
Carrying a secret that could be exposed at any moment, a turbulent youth romantic comedy begins!
