She is the eldest daughter of the disfavored Murong family, living like a forbidden secret in Qinxin Garden. She doesn't believe in love, yet marries a man she has met only once. He is a mysterious merchant who controls the five great trading houses of the realm. In a turbulent and complicated age, he marries her because of a promise. He doesn't love her, but agrees to protect her for the rest of her life. Time passes, the years turn, and feelings quietly take root between them, their souls bound by a lingering tie. Just as they are about to confess their feelings, the "her" in his heart appears. What follows is an eventful night: she is poisoned by a love bug, but who is responsible? His hesitation extinguishes her only remaining hope for love. She means to flee far away with her tender, uncertain feelings, never expecting to become entangled with him in another emotional struggle.
