A time traveler who lost his memory became the innkeeper, and found out that he was the 48th "Hong surnamed shopkeeper" - all the previous 47 people had disappeared. In the process of raising money to pay off debts, cracking the system, and finding out the truth about his ex, he formed a life-and-death relationship with the account girl, the dishwasher who pretended to be stupid, the female resident who investigated the case, and the cook with a severed finger. In the end, he chose not to escape from the inn, but to turn the inn into a home.
