Spoilers for Single's Inferno season 5 episodes 1-10 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. Judging by the season thus far, it seems the new group of pageant queens, models, and athletes has lived up to the hype. Below, read on to learn more about Single's Inferno season 5, including how to follow them on Instagram, and their ages and professions...if they've been revealed on the show.
The Women of 'Single's Inferno' Season 5
Park Hee-sun
Park Hee-sun, 22, is a college student studying information systems at Carnegie Mellon University in Pennsylvania. At the time of season 5's filming, she was also interning at a global cosmetic brand working in customer relationship management.

She explains that she's not used to being single, and wants someone to steal her heart and "end this single life."
