As a rookie in the police world, Qin Shuhao inexplicably joined the angel group to eradicate demons, and found out that the group leader was Lin Musen, his high school best friend after five years of absence. In the process of getting along, the two understood their respective hearts and put aside the worldly world to be together.

Shu Hao, I love you, I am leaving, let me listen to your singing again.
