He is a rich young man who has been emotionally hurt, and she is a stupid angel who made a mistake and was sent to the earth.
By chance, the young man from the rich family mastered the "key" for the idiot angel to return to heaven. It is not easy to get back this "key", only by being obedient.
Hehe, idiot angel, just get ready and I won't let you go until I've served you well!
