After studying the piano for more than ten years, I suddenly lost my ability to play the piano. Tan Shanxing was puzzled as to why the dulcimer, an instrument so unpopular, happened to meet a master in a small piano store and was taught by someone. I don't accept it, I really don't accept it. Yu Guan, the owner of a music store, is a recluse in the city. He suffers from social phobia and severe occupational diseases. When he meets a good young man, he doesn't know how to greet him.

Thinking about it again and again, it turns into an out of control full of like and love.
