The heroine was born with a heart disease. She didn't want to leave any regrets in the end. She came to school and was seated with the hero on the first day of school. Many people advised her not to mess with the hero. The hero is the school bully. Gradually, she did not think that the hero was a bad student in other people's words. Slowly, the hero also developed a liking for the heroine. They went to perform guitar and picnic together and were divided into a group. The hero always came to take the heroine to and from cram school and accompany the heroine to watch movies. They went to the beach to relax together and agreed to plant a plum tree together. Every Spring Festival, they make their own wishes under the plum blossom tree, but the heroine breaks her promise. The heroine stays at the age of 19 forever. The hero also suffers from depression and autism in the past two years because of the heroine's departure. On the New Year when the hero was 22 years old, he sat under the plum blossom tree and watched the firecrackers and thousands of lights before passing away.
Intention: That year he broke off a cold plum for me with his own hands and said that we would enjoy the wind and snow together year after year. But now the plum blossoms have bloomed a thousand times. I walked all over my hometown and saw only fallen leaves and people who could never wait to come back. Let this plum blossom tree bear witness to our last agreement. We cannot go together in life, and we will go together in death.
