Su is the only daughter of Chairman Kim, the head of a powerful chaebol family. At 25, she lives a life dictated by responsibility, expectations, and silence. Practical and controlled, she has learned to suppress her desires in favor of duty.

Eom Seonghyeon is 26, an intelligent and reserved man with no known background. He survives by working in the criminal underworld, carrying out dangerous tasks with unsettling calm. He keeps people at a distance, convinced that attachment only leads to loss.

Their paths first cross late at night at a convenience store—just a glance, nothing more. Days later, fate pulls them together again in a hospital hallway, where a small, silent exchange leaves a lasting impression. Neither asks questions. Neither shares names.

As their encounters continue, they begin meeting intentionally—always at night, always away from watchful eyes. Su hides her identity as a chaebol’s daughter. Seonghyeon hides the darkness of his work. Their love grows slowly, built on quiet conversations, routine, and unspoken understanding.

Unknown to Seonghyeon, Soo is promised to a future she did not choose. Unknown to Su, loving him may one day drag her into a world she can never return from.

Their story unfolds in the space between secrecy and truth—where love exists, even when it is never meant to.
