Su Wan, a surgeon, pretends to be the missing wealthy heiress Xia Xing to save her terminally ill brother. Gu Jingshen, heir of the Gu Group (rival of the Xia family), disguises himself as a playboy to uncover the family traitor. Bound by a commercial marriage, Su believes Gu is a real libertine, while Gu thinks Su is the real heiress—until their masks crack: both are "substitutes"—one for identity, the other for "persona". When a fake heiress meets a fake playboy, is the heartbeat growing from lies a habit of substitution, or the awakening of true love?
