For five long years, Tang Zhi Yi lived as Gu Jing Hang’s wife—caring for him through illness, standing beside him in public, and building what she thought was a quiet life of loyalty. But beneath the surface, nothing was real. Not the love. Not the promises. Not even the marriage.

Zhi Yi was never legally his wife. There was no marriage certificate—just a ceremony built on guilt and secrets. She wasn’t the woman he loved. She was a replacement for a girl named Ah Zhi, whose heart (literally) beat inside Gu Jing Hang after a transplant.

To make matters worse, the woman Gu Jing Hang truly loved, Tang Wei Wei, returns—fueled by jealousy, greed, and a need to reclaim both her man and her spotlight. Wei Wei schemes her way into Zhi Yi’s roles, fakes a pregnancy, and manipulates everyone around her—including Gu Jing Hang’s mother and the entire Gu family.
