Intro. Lee Seung-gi is the epitome of perfection: a top-tier actor with a stable marriage to renowned actress Go Minsi. However, behind the spotlight, their four-year marriage has grown hollow and silent, haunted by the absence of a child. Amidst this void, Seung-gi accepts a role in a melancholic romance drama by famed director Kim Jaehee. He is paired with Karina Yuu, a rising star with a magnetic and ethereal energy.
Initially, Seung-gi dismisses their spark as mere professional chemistry. However, Karina’s bold gaze and touches that feel far too real begin to crumble his walls. The acting that was supposed to end when the director yelled "cut" starts bleeding into their off-screen lives. Seung-gi finds himself trapped in a dangerous dilemma: remain loyal to a fading marriage vow or surrender to a new passion that makes him feel "alive" for the first time in years, at the risk of destroying everything.
