Time flies and no one knows how many years have passed. Lin Cheng wonders if he had not chosen this high school, had not entered this campus, or had not joined his team as a member, then everything would have been different... If there had not been this difference in thoughts at the beginning, and without the later, would the worries that he had buried for many years never exist at all. The relationship between her and him will always be calm and smooth, and they will get along as friends throughout their lives. But what existed was Lin Cheng's thoughts, and what didn't exist were the what-ifs in his mind. At first, when Lin Cheng first met Shen Che on this campus, they were just friends, or even the term friend was a bit far-fetched, just a classmate who had been at the same desk. But later, he was her life, and she was his sunshine... This story is about Lin Cheng and Shen Che, about youth, about secret love, and about you and me... (A newbie, writing for the first time.
