When the protagonist He Yixing was a child, his mother gave birth to him and his sister He Qingyue in an unknown way. But his father already has a wife. His wife had a car accident three years ago and became a vegetable. His mother died of a heart attack, leaving only He Yixing and his sister He Qingyue, who were later sent to an orphanage. The children in the orphanage didn't like them either and bullied them. Fortunately, He Qingyue made money in the orphanage. No, they started living in the house left by their mother.
He Yixing inherited his mother's heart disease. In the second grade, he met a boy who was very kind to her. The boy was very withdrawn in school, and he had been reading a book called "The Little Prince". Later, he met He Yixing, who was equally withdrawn. He Yixing said, "Do you also read "The Little Prince"?"
But He Yixing had to go elsewhere for treatment due to a heart disease. Before leaving, the boy gave He Yixing a necklace with a rose ring. But because the time was so far apart, he had forgotten the boy's name and appearance...
In his sophomore year of high school, he met that boy again. His name is Jiang Chenying. His parents died young and he lives with his aunt.
During this period, He Qingyue also had a girlfriend named Mu En, nicknamed Little Moon. However, the good times did not last long, and He Qingyue died of heart disease.
They went through many hardships, and He Yixing also learned that Jiang Chenying was the boy from his childhood, but He Yixing's heart disease became more serious. Jiang Chenying was also diagnosed with leukemia, and he would not live long without a bone marrow transplant. After He Yixing found out, he voluntarily transplanted bone marrow to Jiang Chenying.
The moment He Yixing died, a cold system prompt sounded [Ding dong, congratulations to the host for completing the hidden mission and letting the target of the attack risk his own life for you three times]
