Zhao Yaru was born prematurely, and Xu Huai was placed in an incubator when she was discharged from the hospital. When Xu Huai was ten years old, he fell seriously ill. The Xu couple learned that they had been looking for their biological daughter. Xu Huai accidentally learned that he was not his parents' biological child during a group blood donation organized by his school at the age of fourteen. Xu Huaibao was recovered the following year.
Xu Huaibao found out that this year his adoptive parents were both involved in a car accident and were sent to the hospital where they died after ineffective rescue efforts. He left behind his adoptive mother and young daughter Liu Xiaoting.
Faced with the indifference of his parents, Xu Huai no longer received a response from his previous efforts to please him. His personality gradually became introverted and he gradually no longer expected his parents' love.
Xu Huai has returned to the Liu family and met Liu Xiaoting. Later, he had a love-hate relationship with Xu Huaibao at school, which started the mutual redemption between the two.
