About

1. Locations. Inferno: The island where the contestants stay. Here, they cannot reveal their professions or ages and must appeal to others solely through conversation. Everyone eats meals together in Inferno. Men's and women's dorms are separate, and contestants are free to talk to the opposite sex. Paradise: A luxury hotel where contestants go if they win a game. In Paradise, they can reveal their professions and ages. They return to Inferno after one night. 2. Games. Physical Games: Winners of intense games like running or wrestling are granted privileges such as the right to choose a partner for Paradise or a special meal date. 4. Catfish. Attractive new contestants who appear midway through the show shake up existing love lines and bring tension to a peak. 5. Final Selection. Once the schedule ends, contestants can leave the island with the person they want. Both must choose each other for a match. 6. Reunion. After the final selection, the cast members gather to watch the broadcast and chat. They share behind-the-scenes stories and honest feelings. They talk about real-life couples and hang out like a school retreat. (Participation is optional; they can choose to just focus on their relationship in reality instead.) 7. Others. Panelists: Hanhae, Kyuhyun, Dex, Hong Jin-kyung, and Lee Da-hee. They watch the footage of the contestants from a studio in Seoul, discussing and making predictions. Host: The host also acts as a referee. The host is a female voice-over, and games proceed according to her directions. She explains game rules and announces important facts. She is never seen in person. She guides the situation solely through her voice, acting as the PA system.
