Now that Single’s Inferno Season 4 has made its debut on Netflix, you’ll most likely want to know exactly who’s in the cast. While there’s plenty of hype, fans of the reality series have one complaint about this year’s contestants.
Since debuting in 2021, Single’s Inferno has grown in popularity, taking place in South Korea where a group of hopeful singles are left on a deserted island known as ‘Inferno’. Here, they have to fend for themselves and don’t have access to electricity.
Their goal? To leave Inferno for a luxury island named Paradise – but the only way to do so is to find a match. Season 4 Part 1 dropped on Netflix on January 14, with new episodes set to land every Tuesday until the grand finale.
Once again, Hong Jin-kyung, Lee Da-hee, Kyuhyun, Hanhae, and Dex have returned as hosts, but what about the rest of the cast? Here’s who we know so far.

Single’s Inferno fans have one complaint
Single’s Inferno typically has 12 contestants, meaning we’ll have to wait to find out about any others in future instalments. Until then, fans have been busy discussing the cast, but some have taken issue with the fact that the list includes celebrities.
Taking to Reddit, one wrote, “I wanted less micro celebs and influencers, not more.” Another said, “So many actors this time around, not excited for it. Anyway the guys have always been meh every season, looking forward to the girls.”
“Yeah no, it’s only celebrities this time too. I’m kinda not excited now,” added a third, while a fourth chimed in, “Show needs to work on casting non D list celebrities.”
However, others are excited for the drama Season 4 is set to bring. “I’m looking forward to the double dates that will be added to this season,” said one. “I love how messy it’s going to be.”
