Idol-to-actor moves keep coming fast this week, and now it’s ZEROBASEONE’s turn. Kim Ji Woong has been confirmed as the lead of an upcoming police investigation drama tentatively titled “Siren,” stepping into a role that pairs chaebol privilege with detective work.

From K-pop Stage to Police Academy Student

The confirmation came on September 4, when JTBC Entertainment News first reported the casting and Kim Ji Woong’s agency, Nest Management, verified it shortly after. In “Siren,” he’ll play Do Yoon, a third-generation chaebol heir who’s also a police academy student — a character whose privileged background collides with the grittier reality of criminal investigation.

The story centers on Do Yoon teaming up with an ace detective from an ordinary background to crack a string of cases, setting up the kind of contrasting-worlds dynamic that’s long been a reliable engine for Korean crime dramas.

A Multi-Format Bet Worth Watching

What makes “Siren” stand out isn’t just the casting — it’s the format. Developing the same story across film, mid-form, and short-form content is a growing strategy in Korean entertainment, letting a single IP reach audiences through different viewing habits rather than betting everything on one release window. Pairing that experimental format with director Oh Ki Hwan, known for genre-driven storytelling on “The Defects,” suggests the project is aiming for something more ambitious than a standard procedural.

Why This Casting Matters

Kim Ji Woong joins a growing wave of idols using their group platform as a launchpad into serious acting roles. Landing a lead position this early, paired with a director who has genre credibility, gives him a real shot at establishing himself beyond ZB1’s idol image — assuming the project delivers on its ambitious multi-format vision.
