My Daughter Is Critically Ill, My Wife Uses the Life-Saving Money to Buy a House for My Brother

My wife is a helper. I am willing to sacrifice everything for my brother, including our little family and our five-year-old daughter. I thought she was a mother who would always have the last trace of motherly love for her daughter. Unexpectedly, she used the money from her daughter's heart transplant to help her brother buy a house. She said, "Miaomiao is just a daughter anyway. It's better to spend the money on this short-lived ghost than give it to my brother!" This time, I went crazy.
