‘Single’s Inferno’: Season 4 Cast of Netflix Dating Series Revealed & More Updates
Single’s Inferno has returned for its fourth and hottest season yet.
Ranking in Netflix’s Top 10 in 29 countries after its Season 3 premiere last winter and now the first Netflix Korea unscripted series to be renewed for a fourth season, the Korean reality program is bringing the next batch of singles to Inferno island, where they must muster eight days of new friendships, potential lovers, and emotional breakthroughs.
Touted for its more coy approach to reality TV, the contestants delicately juggle pursuing the people that pique their interest. More often than not, friends are often in contention with one another, vying for the same guy or girl unbeknownst to each other due to their anonymous bidding system. The result? An emotionally and physically tense show, cultivating the highs of a more real-feeling courtship process.
The show is spurred on by the panel of hosts who accompany the program each season, various Korean actors and personalities who watch the show with you in real-time and add their own incredibly entertaining feedback. Keep reading to learn everything we know about the upcoming season.
How does this Single’s Inferno work?
The concept is simple: A group of single women and men meet and live on a “deserted” island, known as Inferno. Over the course of eight days, the contestants cook meals together, play competitive group games, and ultimately get to know one another on a more casual basis.

The goal of the show is to get off Inferno and make it to Paradise, finding your perfect match by the end of the eight days. The only way to go to Paradise is if a couple successfully bids for each other, making them a match. At Paradise awaits five-star hotel rooms, endless room service, hot tubs, massages, you name it. There, the couples get to know each other on a more personal level.
Each season has only a handful of opportunities to go to Paradise, so who contestants choose to try to match with must be done strategically, weighing the question: Are you going to take a chance and try to match with the person who might not be interested in you, or are you just trying to go to Paradise?
Oh, and one more thing. The contestants cannot reveal their ages or professions to one another until they are in Paradise. And what’s said in Paradise must stay there.
