Fang Yusheng, a senior lecturer in the Fine Arts Department, is gentle and elegant.
Li Yu, a new recommended student from the Art Department, is handsome, kind-hearted and has excellent grades.
Fang Gang, Fang Yusheng's son, met his father's student, Li Yu, when he was seven years old. From then on, he was attracted by Li Yu's melancholy and delicate appearance.
Meili, Fang Yusheng's wife and college classmate, has been staying at home to take care of her husband and children after marriage.
Fang Yusheng loves his career, his wife and son, and his family even more. He thinks life is like this, although it is dull, it is the most real.
Until they met in the studio that summer, Fang Yusheng's ordinary life was no longer ordinary. He realized that he had never truly lived or loved. Only Li Yu, whose almost dry heart showed signs of beating again.
