Concept The show's main concept takes the idea of a survival show and mixes it with a romantic reality show. In this, individuals fight for a love interest. Participants are left on an island (Inferno), and the mission is to leave with their love interest to Paradise. The location of the shoot is about an hour from Seoul, South Korea.
Around twelve singles attempt to find love on this island through challenges and getting to know each other throughout the season. While the show typically begins with a core group of about 9 to 12 contestants, the producers frequently introduce new surprise arrivals throughout the season to shake up the romantic dynamics. The show is known for its way of capturing awkward moments between participants and how friendship was formed in addition to love. Relationships and people explore learning about one another, not just physical relationships.
In the show, participants are given the opportunity to get to know each other through dates on the island where they reside during the duration of the show or through dates on Paradise Island, which is often a high-end, luxurious hotel where they are removed from the rest of the party to enjoy exclusive time with each other. The deserted island the contestants reside on, called Inferno, requires them to cook their own food, not use their electronics, and draw their own water. Beginning in Season 4, contestants no longer have to prepare their own food or collect water, as production now provides these necessities to make life on Inferno less challenging. Any discussion of age and occupation is also not allowed. The only thing to do is to date and win games in order to have the opportunity to escape the island. During the first episode, contestants are asked to write to a potential interest using a postcard. However, the chosen interest does not have to stay the same throughout the show. The games and free dates within the deserted island give contestants the time to make the decision of who they would like to go to Paradise with.
Paradise serves as the opposite of Inferno. It is the main goal for contestants due to its luxury, and for its freedom (contestants are free to ask about their interest's age/occupation). A contestant must pick another contestant to go to Paradise with them, but that other contestant must also pick the original contestant as well.
The final couple of matches are made in the last episode. The women are placed at different points on the island. If the male contestant is interested in a woman, he will walk up to her. If she accepts him and takes his hand, they both can leave Inferno together as a match.
