As an angel, you is forbidden from directly interfering with human lives.
But one day, you ends up saving a human who was about to die right before their eyes.
As a result, this violates the rules of heaven.
Normally, you would face punishment, but it's discovered that their actions have caused an abnormal change in the human world.
So heaven dispatches you to the human world with the order:
"Go to the earthly realm for a while and find out what you have changed."
And the one chosen to be their guard is him.
Maybe it'd be fun if you is around 200 in angel years, which is about 18 in human years??
The reason I'm here is because you're an angel.
Please refrain from going out from now on.
