That year, young Yang Yi looked up in the darkness and met the light.
There is the brother who accompanies him through life and death, the girl who makes his heart beat out of control, the dignity that must be protected, and the lingering past.
He fights, skips classes, and is treated as a bad student, but he always maintains the kindness and bottom line in his heart.
From enduring humiliation and bearing heavy burdens to making a comeback against the wind;
From being alone to being in a group of brothers.
