A meticulously planned car crash turns Su Wan from the adored eldest daughter of the Su family into Gu Yanchen’s prisoner. Because the evidence has been tampered with, she is branded the culprit who tried to kill her younger sister. Chained up in a lightless basement, she is forced to cut off her long hair and imitate her sister Su Yao’s words and mannerisms, becoming a substitute for him to vent his hatred on.
Gu Yanchen, the cold CEO who controls the economic lifelines of half the city, uses Su Yao’s life to keep Su Wan at his side. He tramples her dignity in the cruelest ways, unaware that his possessiveness has already twisted into feelings for the defiant substitute. Hidden inside the cuff of the chain around Su Wan’s wrist is a micro USB drive left by her father, containing secrets powerful enough to topple Gu Yanchen’s business empire. A voice recorder sewn into the hem of her clothes is her only weapon for uncovering the truth and settling the blood debt.
Humiliating entanglements at banquets, the threat of her identity being exposed in front of old acquaintances, and schemes brewing in the shadows make this imprisonment in the name of hatred all the more mysterious. As the truth about the car crash gradually comes to light and the hands behind the web of corruption bare their fangs, Su Wan finally refuses to endure it any longer. She will break free of this cold cage, reclaim everything that belongs to the Su family, and make everyone who wronged her pay in blood.
But when the blade of revenge turns toward Gu Yanchen, and misunderstanding and hatred begin to fade, she realizes that their battle, supposedly an act of “imprisonment,” has long been tangled with a bond neither can let go of. A rose stubbornly blooms inside its cage. As love and hate pull them in opposite directions, can they break through the haze and find redemption in each other?
