Synopsis

Kyung-hee, a quiet office worker trapped in a monotonous life, receives a mysterious email from someone calling himself "master." What begins as curiosity soon spirals into obsession as nightly tasks push her boundaries—first with lingerie, then nudity, and an ever-deepening surrender to a stranger’s unseen gaze. As her body responds to each command, she begins to wonder: is she being watched, or is she becoming someone else entirely?
