In the variety show, a couple will manage an inn with a company of friends as the guest for 20 days. The Inn focuses on the hospitality of two innocent couples towards their friends (guest) who spent 20 days running the inn together, and opening up to each other by sharing stories of their lives and their own past. On certain episodes, the production team invites mysterious guests as "volunteers" and the former will work together with the five "masters" in the show. Once guests have checked into the inn, the production team will give each of them a star, and guests will vote for one of their favorite employees from among the three at the end of their stay.
