に～づまはセーラー服 ～ダーリンは担任教師～

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.
