After years of speculation and anticipation, the popular drama Signal is finally getting a second season.

Lee Je Hoon on reuniting with the cast
During a group interview held on June 2 in Seoul’s Samcheong-dong, Lee Je Hoon opened up while promoting his upcoming film Big Deal. The conversation quickly shifted to Signal. And the actor spoke warmly about reuniting with co-stars Kim Hye Soo and Cho Jin Woong.
As quoted by AllKpop, “It’s rare (for a cast) to reunite and act together again after 10 years. For me, it’s something I’ll remember for the rest of my life,” he said.
Lee Je Hoon expressed that reuniting with his co-stars after such a long time brought a sense of comfort and renewed inspiration. He noted that everyone had matured over the years and felt the atmosphere on set had become more relaxed compared to the past.
A confident promise

With the original trio back and production already underway, Signal 2 is shaping up to be one of the most anticipated drama sequels in recent memory. Fans who have waited nearly a decade for answers may finally get the closure they’ve been hoping for.
What fans can expect in Season 2
Signal originally concluded with several mysteries still unresolved, particularly the fate of detective Lee Jae Han, played by Cho Jin Woong. The series followed detectives from different timelines who collaborated to crack long-forgotten cases. They get linked by a walkie-talkie that allows them to communicate across time.
Season 2 promises to pick up where the original left off. Kim Hye Soo will return as Cha Soo Hyun of the Cold Case Squad. Cho Jin Woong reprises his role as the missing detective Lee Jae Han, and Lee Je Hoon resumes his part as profiler Park Hae Young. Their reunion has raised expectations for a powerful continuation of the story.
