A 300-year-old angel accidentally saved a sunshine boy during a mission. Later, because of saving the boy, the angel lost his magic power. Her sister said: Because you saved the boy, you will be punished with no magic power for six years. During this period, the angel must be with the boy, otherwise the magic power will never come back. The boy adopted her out of guilt for the angel and started a hilarious life in high school with her.
Concept: I came up with it when I saw the angel I drew.
