Gu Yan and Wen Wan were high school alumni. Due to an accident, the taciturn and somewhat withdrawn Gu Yan was attracted by the lively and cheerful Wen Wan, and he has been following Wen Wan silently ever since. Until he transferred to another school, Gu Yan didn't express his feelings. I thought the two were destined to be inseparable, but eight years later, Gu Yan, who had just gotten off the plane, was waiting for someone to pick her up. He accidentally caught a glimpse of someone with a similar appearance to Wen Wan. When he stepped forward to check, he was accidentally hit by the other person, and he discovered that she had changed her name. In order to find out the facts and give an explanation to his youth, Gu Yan left Wenwan's contact information on the grounds that his clothes were clean, and began a journey to chase his wife.
In high school, Wen Wan was traumatized because she met unkind people and helped bad people, so she changed her name as a warning. But she always maintained goodwill, and the little boy she accidentally saved after graduating from graduate school turned out to be Gu Yan's biological brother.
With Gu Yan's personal efforts and the help of his friends, the two began an underground love affair without telling everyone.
