Episode Highlights
Episode 1: A Phone Call That Changes Everything
The story kicks off with Sa-eon receiving a chilling call, claiming that his wife, Hee-Joo, has been kidnapped. What seems like a straightforward crisis spirals into something much deeper. Sa-eon’s detached response to the threat ignites a wave of emotions in Hee-Joo. Struggling with selective mutism and feelings of powerlessness, she decides to take control of her life.
In a bold move, Hee-joo uses the same phone to issue her own threats to Sa-eon, demanding a divorce. Her actions mark the beginning of a transformative journey for both characters, signaling a shift in their strained relationship.

Episode 2: Secrets, Jealousy, and Rising Tension
Sa-eon’s seemingly perfect life starts to crumble under the weight of the blackmailer’s demands. Desperate to uncover the truth, he becomes more entangled in the mystery. Meanwhile, Hee-joo’s unexpected closeness with Ji Sang-woo (played by Heo Nam-joon) fuels Sa-eon’s jealousy.
A cryptic photo sent by the blackmailer heightens the tension, forcing Sa-eon to confront his feelings. The once-distant couple finds themselves in a complex web of emotions, secrets, and unspoken truths. Their evolving dynamic keeps viewers hooked, eager to see how their story unfolds.
