I replaced my sister who died in a car accident and became the daughter-in-law of the top wealthy Gu family.
Gu Huai is gentle and considerate, and everyone says that I have a good life.
Until I found a yellowed medical record in his study——
The cause of my sister's death was heart transplant rejection.
And on my matching report,
Gu Huai's name was written in the donor column.
