🎬 Webtoon to screen: What is 'Field Mouse' about?

On May 20, Netflix officially confirmed the production of its new original series 'The Rat' (literal title), based on the popular Kakao webtoon of the same name. The psychological thriller follows a recluse novelist and a relentless loan shark who team up to hunt down a mysterious man who ruined their lives.

💸 Sul Kyung-gu plays No-ja, a ruthless loan shark who's been tracking Moon-jae for unpaid debts. When they meet again three years later, Moon-jae asks No-ja to help him uncover the identity of the elusive criminal.

🔥 New duo, high expectations

This marks the first-ever collaboration between Ryu Jun-yeol and Sul Kyung-gu—two of Korea's most critically acclaimed actors. Their intense screen presence is expected to elevate the high-stakes cat-and-mouse thriller to a whole new level.
