"It doesn't matter whether I like it or not, as long as she likes it." This is what Xia wrote in the preface of his math book when he was a freshman in high school. Liking Su Juan is a secret of his, something he wants to hide. There is no boy who doesn't like girls, but he accompanies girls through youth and into maturity.
From the age of six to thirty, from the tenderness of youth to the ability of maturity, it can be said that Su Juan has Xia in his youth, and Xia Zai has Su Juan in the rest of his life.
Concept: Youth is beautiful and innocent, a time that many people miss.
