Whether they were the “endgame” couple we rooted for or the ones who sparked a thousand memes, the stars of Single’s Inferno are naturals at staying in the spotlight long after the final campfire. While we’re currently obsessing over which Season 5 couples actually made it in the real world, it’s time to check back in with the OGs. From Season 1 through to Season 4, we’re catching up with the islanders who survived the hottest place on earth to see what they’re up to.

Season 1

Song Ji-a 

Once the it girl of Single’s Inferno, Ji-a took a hiatus following a controversy regarding the fake luxury items she wore on and off the show. However, she has since managed a steady comeback. Now a prominent lifestyle content creator, she has amassed hundreds of thousands of subscribers on Youtube, where she shares travel vlogs, “Get Ready With Me” videos, and unboxing content. Honestly, her ability to pivot back into our feeds is the kind of character arc we live for.

Kim Hyun-joong

The fitness enthusiast who escaped the Inferno with Ji-a has successfully turned his passion for wellness into a career. Between launching his own fitness hub, Mood Gym, and a dedicated skincare line, Abits, Hyun-joong has truly entered his entrepreneur era. When he isn’t managing his ventures, he’s active on Instagram, serving up a mix of gym progress and stylish fits.

Kang So-yeon

So-yeon is still the ultimate multi-hyphenate athlete of the franchise, and we’re convinced she has more hours in her day than the rest of us. In 2022, she made her long-awaited return to the music industry with the single “Loca Loca”—a nod to her origins as a K-pop idol in the co-ed group WE. She showcased her athleticism once again in 2024 as a contestant on Physical:100 Season 2, and continues to compete in professional amateur golf tournaments alongside football and tennis. Beyond her personal training, she has successfully moved into business as the founder of the boxing gym HitFit Boxing.

Choi Si-hun

Si-hun has traded the island’s drama for scripted sets, notably starring in the Apple TV+ workplace drama The New Employee. His personal life also made headlines in early 2025 when he married singer-songwriter Ailee. We are still quite obsessed with the photoshoot they did to mark the occasion, which naturally featured their puppies.

Cha Hyun-seung

The dancer-turned-actor has had a whirlwind year that puts everything into perspective. After appearing in Physical: 100 and the film No Mercy, Hyun-seung faced a major health battle following a sudden diagnosis of acute leukaemia in late 2025. In a move that gave us all a collective sigh of relief, he announced his full remission by December. We’re all wishing him a smooth recovery and hoping he gets back to his freediving and surfing adventures soon. 

Moon Se-hoon

If you thought Se-hoon was persistent on the island, his professional drive is even more intense. He’s currently building a hospitality empire that includes Moonbo Hotpot, Onlygo&Co, and the BAY Korean BBQ Club. Not content with just the dining scene, his ventures extend to a florist shop, Flcha Sinsa, and his own brands of Makgeolli and Kimchi. Between managing his growing portfolio and posting his adorable dog on Instagram, he has also returned to the dating show circuit as a guest on 60 Minutes to Love. He’s booked, busy, and remarkably well-fed.

Season 2

Kim Jin-Young (Dex)

Arguably the most successful breakout star of the franchise, Dex has successfully transitioned from a career in the military to a versatile entertainer. He’s now a familiar face on the Single’s Inferno panel, where his witty, insider perspective adds a unique layer to the commentary. His acting CV is growing rapidly, with roles in Netflix’s Zombieverse, the survival show Bloody Game, and the action drama The Defects. When he isn’t on a film set, he is likely uploading lifestyle content to his YouTube channel for his dedicated subscribers.

Nadine Lee

As the first Korean-American on the show, Nadine brought a fresh perspective and distinctive charm to the show, adding something the series didn’t even know it was missing. She’s a total academic weapon, having graduated from Harvard in 2023, with a degree in Neuroscience and a minor in Computer Science—a combination that makes our head spin just thinking about it. Whilst she was famously a pre-med student on Single’s Inferno, she has since evolved into a corporate weapon, working as an analyst at a consulting firm focused on healthcare strategy. When she isn’t navigating the high-stakes industry, she regularly shares outfit and lifestyle updates with her followers. It’s a classic case of beauty and brains, though her puppy Zobby arguably still steals the show on Instagram. 

Shin Seul-ki

After graduating from Seoul National University with a degree in piano, Seul-ki decided to swap the concert hall for the screen—and the pivot paid off. She made a notable debut in the psychological thriller Pyramid Game and has since starred in the historical fantasy The Haunted Palace. Her KBS Drama Award for Best New Actress and an SBS Drama Award for Best Supporting Actress are official testaments to her talent. Between filming schedules, she has been frequently spotted at Dior events.

Choi Jong-woo

Jong-woo has seamlessly continued his reality TV streak since leaving the island. He’s been spotted trading the beach for the pitch, making appearances for the celebrity football team Lion Hearts FC for the show Let’s Play Soccer, and even popped up on the matchmaking series 60 Minutes to Love. He has also dabbled in acting, making his debut in the short-form drama Time Running. Between takes, he keeps his YouTube subscribers updated with travel vlogs while his Instagram remains a go-to for consistent outfit checks.

Choi Seo-eun

Seo-eun is the definition of “doing the most” in the best possible way. She’s recently been busy expanding her resume into the world of acting with roles in the Amazon Prime spy thriller Butterfly and the suspenseful K-drama The Manipulated. Stepping off the screen and onto the stage, she even made her theatrical debut in October 2025 at the Daehak-ro Theater Joy Seoul. When she isn’t busy performing, she’s serving up aesthetically pleasing mukbangs and outfit inspiration.
