When Wang Muyu was seven years old, his parents adopted him a "brother"
Since then, something has been wrong with Wang Muyu
I don't know who I'm talking to every day
He said this is his friend
But in everyone's eyes
He's talking to the air
Mom and dad tried to take him to the doctor to no avail
Slowly, Wang Muyu's imaginary friend disappeared
Only his brother Wang Chenyang is left in his life
But one day, he also disappeared. . .
