High school freshman Jiang Yu went from being the neighborhood's model child to a problem student in the eyes of his teacher, zoning out in class, slipping in grades, and refusing to communicate. Everyone said he had gone bad, but no one saw him still studying desperately under his desk lamp at two in the morning. His mother's reproaches, his father's silence, the midnight efforts, the grievance of being misunderstood—until his teacher asked if he was very tired, and the boy's facade of strength for half a year finally collapsed. And his parents truly began to change starting from seeing that clumsy back still flipping through textbooks in the middle of the night. This is a journey of growth about being seen, being understood, and reconciling with oneself.
