Cora comes from an ordinary middle-class family. On a rainy night, she is first abandoned by her fiancé Finn, and then entrusted by her ailing father to Neo as someone under his guardianship. Neo is a cold, sharp minded lawyer and the man in power behind the Garcia family, the richest family of all. Forced to live under the same roof with him, Cora finds herself constantly confronting his presence. Neo is rational and dangerous, a man who never lets anyone get close to him easily—yet Cora seems to be the exception. Through repeated clashes, Cora chips away at Neo's indifference with her intelligence and subtle allure. Meanwhile, Neo struggles between restraint and desire: he wants to push her away, yet cannot ignore the growing pull he feels toward her. Gradually, Cora realizes that what she wants is not merely revenge on Finn, but to take control of her own fate—and to shake the heart of this untouchable man. But just as Neo finally begins to lower his guard, Cora discovers that deep in his heart there exists someone else: a “white moonlight” who has long since gone to Europe.
