For many of this season’s cast members, Single’s Inferno 5 isn’t their entertainment industry debut. Several have appeared on variety shows, modelled, or hosted events as emcees. These cast members have also made their K-Drama acting debuts:
1. Jo I Geon
As one of the mid-season “game changers,” Jo is new to Single’s Inferno 5 viewers, but he might be the best-known actor in the cast. Jo signed with Big Boss Entertainment in 2024, and since then, he has acted in two K-Dramas.
Jo played the supporting role of Yun Ji O (Lee Seo Yeon’s husband) in Netflix’s 2024 K-Drama The Trunk, where he had some very steamy scenes. He also played the supporting role of Cho Seong Il in the 2025 K-Drama Someday of Me.

In Episode 1 of Law and the City, Choi plays a woman named Lee Jeong Min who goes on a date with the male lead, Ahn Ju Hyeong, played by Lee Jong Suk. Unfortunately, that onscreen romance didn’t work out too well!
