I didn't intend to write a formal novel, but I just wanted to write something to commemorate it when I was just starting to fall in love. The tender and simple love was lingering in my heart. Look now, I am already in the second year of junior high school and you are already in the second year of high school. In a few years, we will all grow up and our youth will pass away. There is no need to be sad about the passing of youth. It is enough to have such beautiful memories. When you grow old, please don't forget the campus with red walls and white tiles and the promise made under the cherry blossom trees. My boy, under the cherry blossom tree of youth, we will see each other again and again! Jin commemorates my childhood love with this article.
