Once a playboy and a handsome one at that, Morishige Jun'ichirou changed his ways after a certain incident. Now he is a young teacher who sports a magnificent beard and a perpetual smile in his eyes - ordinary at first glance, but surprisingly sharp when it counts.

Misora, a high school girl and his fiancée, has adored him since childhood.

The two love each other deeply. But Jun'ichirou's great-aunt, who knows all about his past, has other plans. She summons him to teach at the all-girls school where she serves as principal. As part of the arrangement, Jun'ichirou and Misora take up residence in the faculty housing on campus - effectively living together as husband and wife.

At the academy, he meets three students: each strikingly eccentric, beautiful, and a troublemaker in her own right.

Can Jun'ichirou resist their every advance and protect his sweet newlywed life with Misora?
