I only went to collect a debt like usual—
but because of a magician’s mistake, Hermie ends up shrinking to the size of a palm!

Instead of offering a way to reverse the spell, the magician makes an outrageous suggestion:
“Why don’t we sell you to the kingdom’s greatest collector, Froy, and pretend you’re a fairy?”

Reluctantly, Hermie begins an unwanted “fairy life.”
But the infamous collector turns out to be… why is he so handsome?

A dangerously delicate cohabitation where her true identity could be exposed at any moment,
his gaze both warm and perilous.

Can she survive in her tiny body?
Or will she unknowingly become his most precious collection…?
