Summary

Nao works at the Kotoshiro ryokan, which is managed by his grandmother after his parents’ deaths. It’s not a profitable business, but one day he got a loan from the Morikawa group... And also a bride!? Sure, his fiancée Mihono is extremely cute, but both of them are still students. They knew little about love, much less marriage. Their personalities don’t seem to be a good fit and their time together was strained from the start. Under the eyes of his classmates and the ryokan’s staff and guests, will they understand the true meaning of love and marriage? [From Hau~ Omochikaeri!]
