Eimi Satou works at city hall on a small island. There's nothing to do there, and the only way to have fun is to fall in love, meaning everybody gets married in their 20s. However, after a bad experience with her ex, Eimi is 28 and still single, which makes life rather uncomfortable. One day, a man from Tokyo called Manabu arrives on the island and ends up staying at Eimi's house. He asks whether she'll consider marrying him if Manabu can satisfy her in bed. Eimi has never had much interest in physical pleasure, but for some reason, Manabu sets her blood aflame... This is a slow-burn love story between a workaholic and a reticent young woman, neither of whom have had much luck with romance. If everyone else can do it, why can't they...?
