Mei no Naisho revolves around the life of the title character Mei Haruna, an effeminate young boy who was raised by his witch mother as a girl, and always thought of himself as female. His mother was the only family he had, so after she died, he transfers to an all-girls high school and resides in the school's dormitory with his familiar Abel, who is talking cat, and his roommate Fuuka Honjou, who is a member of the public morals committee.

Shortly after arriving at the school, his new friends discover after a magical display in the dormitory community bath that he is actually male, though this comes as quite a shock to him despite him being aware of the physical differences between him and normal girls. Despite him being found out, and after some helpful intervening of the perverted student council president, the principal of the school decides that he can stay at the school.

The next day, Mei comes to school with Fuuka and apologizes for hiding the fact that he was a witch, and informs the others how he is apparently male. The other students quickly accept him as one of their own, and are impressed how he can use magic.

Kayama Miharu enters her new middle school and immediately becomes friends with Mori Mizutama, a very cute guy she first takes to be a girl but is really a boy. However, though Miharu likes Mizutama, she cannot tell him, especially ever since the older Kawagoe (yes, a boy) seems to have taken Mizutama's interest instead. Miharu tries to be cute for Mizutama, but finds it practically impossible, as he is both more talented at home economics and more cute than herself.
