In order to raise money for his sister's surgery, Chu Wenxing accepted a bizarre commission - to go to the abandoned Qiyun Mansion on the outskirts of the city to record the strange patterns on a gloomy wooden coffin sealed by iron chains.
He didn't expect that he accidentally triggered the ancient evil contract of "borrowing one's life" while rubbing the pattern. There was no body in the coffin, only Yan Linyuan in old auspicious clothes. He is a soul that has been betrayed and suppressed for hundreds of years, and he is also the only "lock" in this deadlock.
The forced cohabitation life is full of strangeness. Chu Wenxing relied on his family's rhinoceros horn hairpin to suppress the "yin pupil" who might go berserk at any time, while Yan Linyuan used his calmness and insight that spanned the ages to accompany him step by step deeper into the shadow of the modern city. From testing each other to trusting each other in life and death, the two teamed up to uncover a dusty tragedy of the Republic of China, and uncovered the evil spirits behind the dark marriage.
When the contract comes to an end, should you surrender your life or burn your shackles? In the long night, the two hearts looked at each other, lighting up the strange things, and also illuminated the deepest obsession and redemption in each other's hearts.
Purpose: To explore the spirit of resistance of individuals in the face of despair and fate, and to demonstrate the power of mutual redemption through the soul bond that spans yin and yang. Under the shell of suspense and fantasy, it expresses awe of life, the pursuit of the glory of human nature in traditional folk customs, and the positive values of breaking away from feudal shackles and sticking to one's heart.
