At the “CJ ENM Content Talk 2025” event held on February 10 at CJ ENM in Mapo-gu, Seoul, Park Sang-hyuk, head of the Channel Business Division at CJ ENM’s Media Business Division, officially announced the production and scheduling of “Signal” Season 2.
Through a video message, actress Kim Hye-soo shared, “Both the cast and production team are doing their utmost during filming. Please show lots of love and anticipation for the new ‘Signal’.”
Production company BA Entertainment has been working on Season 2 for a long time with writer Kim Eun-hee, and the timing of its release coinciding with tvN’s 20th anniversary in 2026 makes it even more significant.
Season 1: An Unforgettable Masterpiece
Premiering in 2016, “Signal” Season 1 starred Lee Je-hoon, Kim Hye-soo and Cho Jin-woong, captivating viewers with its gripping narrative and the cast’s stellar performances.
The drama heightened immersion by basing its cases on real-life unsolved crimes, such as the “Lee Hyung-ho Kidnapping Case”, the “Frog Boys Disappearance Case” and the “Dentist Mother-Daughter Murder Case”.
Notably, the unique premise of detectives from the past and present communicating via radio to solve cases set it apart. Its immersive storytelling, intense direction and the cast’s outstanding performances made a significant mark in K-drama history.
According to Nielsen Korea, “Signal” achieved an average rating of 13.4%, peaking at 15%, setting its own record as a phenomenal hit. The drama gained massive popularity not only in Korea but also internationally, with fans persistently requesting a second season.
The anticipation for Season 2 grew even stronger due to Season 1’s open-ended finale, which left several unresolved mysteries for the characters—Profiler Park Hae-young (Lee Je-hoon), Detective Cha Soo-hyun (Kim Hye-soo) and Detective Lee Jae-han (Cho Jin-woong).
Season 2 Casting: Original Members Return, Ahn Jae-hong Joins
The core cast—Lee Je-hoon, Kim Hye-soo and Cho Jin-woong—are set to reprise their roles in Season 2.
Director Jang Hang-jun, the husband of “Signal” writer Kim Eun-hee, hinted in a YouTube variety show, “I shouldn’t say anything… but basically, the original actors are all in.” The three actors have also expressed their strong desire for Season 2 in multiple interviews and official events.
Joining them is actor Ahn Jae-hong, who will play a crucial role, bringing fresh dynamics to the existing characters. While details of his character remain undisclosed, he is expected to be a key figure in solving the unsolved cases.
Ahn Jae-hong has previously showcased his versatility through films like “Socialphobia” and “Time Renegades”, as well as dramas like “Be Melodramatic” and “My Dream”. His addition to “Signal” Season 2 raises curiosity about how his character will intertwine with the original storyline.
What to Expect from “Signal” Season 2
“Signal” Season 1 went beyond crime investigation by embedding strong social commentary into its storytelling.
Season 2 is expected to continue this trend, introducing compelling new mysteries and shocking twists. Fans are especially eager to see how unanswered questions from Season 1 will unfold—such as Lee Jae-han’s fate, the altered timeline affecting Park Hae-young and Cha Soo-hyun, and whether the radio connection will be restored.
