Sacrifice Only Brought Doubt

Xia Donghai raises his daughter Xia Tian alone. Her mother is Cheng Xin, who married him against her father's wishes and nearly died giving birth, and the baby was carried off with fluid in her lungs. Cheng Xin's father put her in hospital, put the blame on Xia Donghai and made the two of them divorce. Years on, Xia Donghai falls ill. Treatment means a lung transplant, and rather than leave that weight on Xia Tian he tries to kill himself and is stopped. Xia Tian goes to her mother to ask for help. Her grandfather reaches her before any answer does and sends her away. She comes into the Cheng house afterwards as hired help, looking after Du Xiaolang, the boy her mother had later. Her mother speaks to her the way she speaks to servants. When Du Xiaolang's condition turns bad, Xia Tian agrees to give him her heart, and her grandfather tells her he does not believe her and threatens her over it.
