Did You Know? These "Single's Inferno" Season 5 Contestants Starred in K-Dramas

Single’s Inferno returned for its fifth season with the same sun-soaked tension and slow-burn romance that fans have come to expect. But as viewers settle in, some contestants are already sparking a sense of familiarity—and not just because of their standout edits on the island. A few cast members have appeared on screen long before the reality show, with credits in various K-dramas.

Fans online were quick to connect the dots, with outlets like Koreaboo pointing out that several Season 5 contestants have acting experience, ranging from guest appearances to supporting roles. Here are the Single’s Inferno 5 cast members whose résumés extend beyond reality TV.

Choi Mina Sue entered Single’s Inferno Season 5 with a public profile that immediately set her apart. She was the first runner-up at the Miss Korea 2021 beauty pageant and later won Miss Earth 2022, achievements that helped establish her as one of the season’s most recognizable contestants even before the show aired.

Single’s Inferno Season 5 quickly found one of its most polarizing figures in Mina Sue. She made an immediate impression upon arrival, drawing the attention of multiple male contestants and quickly becoming a recurring topic of conversation among viewers.

Outside the Inferno, Mina Sue has also appeared in several K-dramas. In 2025, she appeared as Lee Jeong-min in the first episode of tvN’s Law and the City, followed by a role as Ye-bin in episode two of Netflix’s Melo Movie. She was also seen in TV Chosun’s 2024 series DNA Lover, where she appeared as a blind date in episode 12.

Woo Sung Min has taken on a much quieter role in Single’s Inferno Season 5, often slipping under the radar despite being present in key moments. While his airtime has been limited, he has notably been positioned as one of the main men catching the attention of fan-favorite Kim Go Eun.

Before working as an optician and helping manage his family’s optical shop, he reportedly acted under the name Woo Ki Hoon, with drama credits dating back to the mid-2010s. His appearances include a supporting role as Kim Min-seok in Solomon’s Perjury in 2016, as well as guest roles in Twenty Again and Missing Noir M in 2015.

He continued acting into 2018, appearing in series such as The Ghost Detective and Cross, and taking on a supporting role as Gong Min-soo in Twelve Nights. That same year, he also appeared in the film Human, Space, Time and Human and in Drama Special Season 9: So Close, Yet So Far, where he played Hong Ki-joon.

Jo I Geon made an immediate impact upon entering Single’s Inferno Season 5 as a late arrival in Episode 5. At 34, he’s the oldest contestant introduced this season, and his arrival quickly shifted the dynamics on the island. Introduced as the new game changer, he was given the opportunity to speak with all the women before choosing Ham Ye Jin and Kim Go Eun to accompany him to Paradise.

Beyond the dating show, Jo I-geon is an active actor signed under Big Boss Entertainment. According to MyDramaList, he appeared in Netflix’s 2024 K-drama The Trunk, starring Gong Yoo and Seo Hyun Jin, where he played Yun Ji-o, the husband of Lee Seo-yeon. Jo I Geon also appeared in the 2025 drama Someday of Me, where he played Cho Seong-il in a supporting role.

Single's Inferno Season 5 is streaming on Netflix.
