Being the only male in an all-female school may seem like a dream come true, but that's not the case for Banji. He must keep his gender a secret in order to continue attending the school, which has become a nightmare for him. Banji's parents value a good education but aren't willing to pay for a co-ed school. Therefore, he has to not only study math and science but also learn how to appear feminine by applying makeup and wearing a bra. Banji's life is miserable as he's not only at the bottom of the social hierarchy but also faces the threat of being exposed by female bullies in the locker room. To make matters worse, he has fallen for a beautiful classmate who he must hide his true self from.
