Musashi Kanata travels to Shiosora Island to claim the hotel and villa left behind by his grandparents, planning to settle the paperwork quickly and return to Tokyo. However, the inheritance comes with a condition he never expected: he must marry one of the three women working at the hotel.

The problem? They are not just potential brides—they are also the reason the hotel operates in near-total chaos. A laid-back manager who avoids responsibility, a shy receptionist whose nervous mistakes cause endless confusion, and a sharp-tongued waitress who never hesitates to criticize him.

Amid messy schedules, confused guests, and small arguments that somehow turn into awkwardly intimate moments, Musashi finds himself stuck in a daily routine far removed from his original plan. The hotel may be chaotic, but the warmth growing within it slowly makes him question something unexpected—

Does he really want to leave?
On Shiosora Island, the inheritance isn’t the only thing he has to decide.
