Xia Wan, an ordinary designer, was forcibly kept in captivity by business tycoon Ling Yao because her face resembled that of the late socialite Murong Xue, and she became a substitute for his obsession. With a contract, she was forced to live in a gorgeous cage, wear a snowflake necklace belonging to the deceased, and endure his uncertainty and domineering control. However, Murong Xue's death was no accident. The bloody buttons, the mysterious warning, and the vicious female partner's pressing steps all pointed to the turbulent undercurrent beneath the calm.
