Single's Inferno솔로지옥

Single's Inferno (솔로지옥) is a South Korean reality dating show on Netflix. A group of singles live on a deserted island, the "Inferno", which they can leave only as couples. Two people who pick each other spend a night at "Paradise", a hotel suite, and only there may they tell each other their ages and jobs.¹⁷ It premiered on December 18, 2021. It was made by JTBC variety producers Kim Jae-won (김재원) and Kim Na-hyun (김나현), and later seasons by Shijak Company, the production company Kim Jae-won founded in 2022. He has directed all five seasons.¹¹⁰ A studio panel reacts to the footage: Hong Jin-kyung (홍진경), Lee Da-hee (이다희), Kyuhyun (규현) of Super Junior and Hanhae (한해), joined from Season 3 by Dex (덱스), who was a Season 2 contestant.¹

There is no prize money, only appearance fees. Season 1's producers said they found the cast through Instagram searches, referrals, applications and street flyers, and had every contestant checked by a psychiatrist before filming.⁸ The first two seasons were shot on Saseungbong-do, an island in Ongjin County, Incheon. A set built there without a permit for Season 3 drew a complaint from an environmental group in 2023, and the producers apologised; DabPop's production feature covers what was disputed and the producers' answers.³⁹

Netflix says Season 1 was the first Korean unscripted series to make its global Top 10 for non-English TV.⁵ All five seasons have made the list since, Season 5 rising highest: three weeks at No. 2, with 45.1 million hours in its biggest week.²⁴ It was the first Korean unscripted series on Netflix renewed for a fourth season, then a fifth, and on February 13, 2026 Netflix confirmed a sixth, again a first for an unscripted title in Korea.⁵⁶¹⁰
