At the age of 14, Qingpu had many secrets. For example, he wanted to own a piano, and he always hid his failing papers in the hole of the old sycamore tree at the door of his home. He once secretly deflated Jiang Fan's bicycle tires as a small revenge, and he fell in love with a person, who was a boy like him. . . . .
When Qingpu grew up from a boy to a man, he suddenly discovered that some people who had made weak vows when he was young never disappeared. However, the person he never dared to expect in the past has been by his side from beginning to end.
Part of the plot is based on a friend's real experience. The reality is cruel, but Xiaoshou will be happy.
