Lin Mu grew up with his sister, Lin Chao, who is congenitally deaf. He is the "little sun" that illuminates the lives of those around him.

Meanwhile, the tall and handsome Lu Rong lost both his parents at a tender age and had since been living with his grandmother who has Alzheimer's disease. He was forced to grow up quickly at an age when he should have been ignorant and oblivious.

Kunqian, an institution that provides learning opportunities for the special community, is where their worlds collide. One a silent soul, and the other a blazing firecracker. With a bunch of schoolmates—a deaf-mute, a visually impaired person, a cerebral palsy patient—they embark together on their chapter of youth.

"Lu Rong, you don't have to put your guard up around me as if I'm some kind of a thief. I have a sister. I get it."

"Okay."
