Meet The Cast Of Single's Inferno Season 4

We're well into Season 4 of Netflix's sizzling-hot Single's Inferno with the streaming platform down to the last few episodes. And those who have watched it would be acquainted with Single's Inferno Season 4's cast members.

If you haven't already caught the last three seasons, the popular reality dating show revolves around a group of young, single South Korean heartthrobs searching for love while stranded on an island (with the exception of the production crew, of course). Without disclosing their age or occupation, they rely on their charm to win over a potential match. Each time they match up, they get to spend a night in Paradise (a fancy hotel), while those who don't remain on the Inferno island.

S2 contestant Dex (Kim Jin-young) returns to the emcee panel, alongside Hong Jin-kyung, Lee Da-hee, Kyuhyun, and Hanhae. Sadly, there's no sight of S3 contestant Yun Ha-jeong, who was rumoured to join the panel for season four.

We round up their names, Instagram profiles, and a few extra details. *Spoilers* on the cast and their jobs below.

The Single's Inferno Season 4 Cast & Their Instagram Handles

1. Lee Si-an

The first contestant to appear, Si-an is a freelance model, and has also been identified as a contestant on the girl group survival show Produce 48. However, she ranked #30 on episode 11 and was eliminated.

She shared that she'd constantly been in relationships, and now that she's single, she wanted to experience a whirlwind romance. The 26-year-old cited her best qualities as her cat-like eyes, kissable lips, and her figure. She's athletic too, having been a competitive swimmer up till the sixth grade.

2. Chung You-Jin

The 28-year-old is a dancer currently pursuing a Masters in dance. She teaches a variety of dance styles, from ballet to other genres, to adults as part of a dance company. While introducing herself, she shared that people often describe her as lovable, cute, and a bit quirky, and that once, at a friend's wedding, six guys showed interest in her. She has a passion for freediving, which makes her feel like a mermaid. When she’s around someone she's attracted to, she subconsciously sweeps her hair, a charming habit she can't help but do.

3. Yuk Jun-seo

Single's Inferno isn't Jun-seo's first rodeo in entertainment. He's also appeared on Netflix's Sweet Home as a military personnel. The 28-year-old, who is an artist, was formerly (like Dex) from the UDT (Republic of Korea Navy Special Warfare Flotilla). He has his own art studio and holds exhibitions, and from his Instagram posts, his other interests include boxing — unsurprising since he's confident about his physical form. He comes across as rather indifferent but shared that some people think he's cute when they get to know him.
