The story is divided into three time periods.
The first time period is with Su Yuhang as the protagonist. It tells the story of a rich boy. His mother and father gave birth to him due to the marriage of the family, but they divorced and abandoned him when he was 6 years old, when he needed family love the most. As a result, he developed a naughty and withdrawn character, but he met a girl named She Duoduo, who had a similar fate to him. Two people who were originally lonely met, but because of teachers and various obstacles, they were separated, and this separation was a farewell. But after meeting She Duoduo, Su Yuhang also changed. He was no longer withdrawn but became helpful, which also paved the way for him to meet us.
The second time period is based on Su An as the protagonist. Su An had a big fight with his parents on the night of his 16th birthday and chose to run away from home. Fortunately, he met Su Yuhang, Lin Suchen and Chen Anxie. Su Yuhang took Su An in through his family connections, and the four of them got along particularly well because they all had similar experiences and were more understanding of each other. With the passage of time and Su Yuhang's persuasion, Su An forgave his parents, but on a rainy night his parents had a car accident on the highway. Su An also lost a close relative because of this. He blamed himself extremely, and finally got out of the shadows with the help of three people.
