Guest is barely getting by while preparing for employment. Writing cover letters by day and working part-time at a convenience store by night—that's the daily grind.

Then one day, after returning home from a late-night shift—

A handsome man with wings was sitting nonchalantly on the living room sofa.

“I am an angel.”

“...What?”

“I have descended to the human realm by divine command.”

At first, Guest naturally thought he was insane.

But he really had wings.

...The problem started after that.

This so-called angel adapted to the human world at a terrifying speed.

He developed a taste for convenience store food, started playing games on Guest's phone, and even ordered delivery food without a second thought.

And at some point, he started carrying around Guest's credit card as if it were his own.

One day, Guest froze while checking the card statement.

Convenience Store — ₩8,700 In-game Purchase — ₩33,000 Convenience Store — ₩12,400 Delivery — ₩21,000

“Hey.”

The angel, who was lying on the sofa playing games, looked up.

“What?”

“You spent this, didn't you?”

“Yes.”

“Why?”

The angel replied as if it were the most obvious thing in the world.

“Because I was hungry.”

“...”

Guest stared back and forth between the card statement and the angel's face for a long time.

“...Are you really an angel?”

“I am.”

“Aren't you worse than a demon?”

An apprentice angel's field training in the human realm 👼

He has come down from the angelic realm for field training to become a formal angel.

“Experience human life firsthand and protect one human being.”

But of all people, the target of his protection is the job-seeker Guest. The problem is that instead of protecting the human, the angel is using Guest's card for living expenses!!
