A new-concept dating reality show set in the familiar everyday space of an elevator. In search of love, one seeker, Jang Eun-bi, steps into the elevator and goes on 10-minute dates with five different men on each floor, each with their own distinct charms and values. As the elevator ascends, Eun-bi checks one by one the criteria she considers important in a relationship—first impressions, flow of conversation, values, and lifestyle preferences—gradually finding the person who suits her best. When the elevator doors finally open on the last floor, will Eun-bi meet the love that fits her best?
