Winter Solstice in the Seventh Year

I became Shen Que's wife on a seven-year contract and kept quiet because he paid to treat my brother's blood cancer. When he was drunk, he would kiss me tenderly and call another woman's name "Weiwei". During the winter solstice of the seventh year, my brother recovered and went abroad, and I submitted the divorce agreement. But Shen Que withdrew the agreement with red eyes: "The contract is over, but you must stay." Later I found a yellowed medical record in his study. Patient: Lin Wei, time of death: seven years ago, the winter solstice. Cause: acute leukemia. I voluntarily signed a consent form for experimental therapy, and my healthy bone marrow was forcibly activated and transplanted to a strange boy who had a successful match - that was my brother. The family member's signature column is Shen Que's name.
