Bai Xi's mother died of cancer when he was in the second grade of junior high school. This blow made Bai Xi heartbroken, but he did not give up and studied hard to get into the best high school in Nanyan. However, the scar left in his heart cannot be erased. During the summer vacation before the first year of high school, he accidentally met Ye Tao, a sharp-tongued girl. Ye Tao thought that the two would not have any intersection. Unexpectedly, on the day of registration, the two were in the same class and were assigned to the same table by the class teacher. Later, she heard about Bai Xi's past events and some rumors and misunderstood. Bai Xi took the initiative to resolve the misunderstanding. During the three years of high school, the two chose science together and worked hard towards their goals, but life was so unsatisfactory that the two separated. When they reunited three years later, they firmly chose each other, growing up and redeeming each other.
