The wait is almost over—tvN’s legendary crime thriller Signal is finally making its long-awaited return, and fans can’t contain their excitement!

On March 5, a buzzworthy post surfaced online, featuring behind-the-scenes glimpses of the cast filming for Signal 2. The images quickly went viral, confirming that the much-anticipated sequel is officially in the works.

In one of the photos, Lee Je Hoon can be seen flashing a playful V-sign, effortlessly radiating his signature charm. Meanwhile, Cho Jin Woong appears with a noticeably fuller figure, sparking speculation among fans. Some believe he may have gained weight for his role, while others suggest it could be a transformation for his character.

Adding to the excitement, actress Kim Hye Soo subtly teased fans by sharing a behind-the-scenes snap on her Instagram story. The photo, featuring a sign that reads "Private Dressing Room - 3, Second Signal, Cha Soo Hyun, Kim Hye Soo," sent fans into a frenzy, fueling anticipation for the show’s return.

Originally aired in 2016, Signal captivated audiences with its gripping storyline, where detectives from the past and present communicate through a mysterious walkie-talkie to solve cold cases. Its massive success led to international remakes in Japan (2020) and Thailand (2022), solidifying its status as one of the most iconic K-dramas of all time.

Now, nearly a decade later, Signal 2: The Second Signal is set to premiere in the first half of next year, bringing back the powerhouse trio of Kim Hye Soo, Cho Jin Woong, and Lee Je Hoon. With the original cast reprising their roles and the hype reaching new heights, fans are eagerly counting down the days until the series makes its grand comeback.
