The Cast of 'Single's Inferno' Season 5: Your Guide to Who's Who and Their Instagrams

Spoilers for all episodes of Single's Inferno season 5 ahead. Netflix's hit dating show Single's Inferno has returned for its biggest season yet. For the uninitiated, the streamer's longest-running Korean reality show is the country's version of Love Island, where beautiful, anonymous singles gather on a deserted island called Inferno to fight for a chance at love. If couples pair up, they can escape to Paradise, A.K.A. date nights at luxury hotels, where they can reveal their ages and professions and get to know each other in private.

Ahead of the show's January 20th premiere, hosts Hanhae, Dex, Hong Jin-kyung, Lee Da-hee, and Kyuhyun teased that season 5's cast—the largest in the reality show's history—were "shockingly honest and expressive" during filming. Now that the season has concluded, it's clear that the new group of pageant queens, models, and athletes lived up to the hype. Read on to learn more about Single's Inferno season 5, including how to follow them on Instagram, and their ages and professions.
