Collector's Cage

I only went out for nothing more than a routine collection, and a mage's mistake turned me into something no bigger than the palm of a hand! Instead of offering a way to reverse the spell, the mage makes an outrageous suggestion, "Why don’t we sell you to Froix, the kingdom’s greatest collector, pretending you’re a fairy?" And just like that, I was forced into an unwanted 'fairy life'. But the infamous collector... why is he so handsome? A nerve-racking cohabitation where Hermy's identity could be exposed at any moment, his gaze warm, yet undeniably dangerous. Can she survive in a body this small? Or will she, before she realizes it, become become Froix’s most treasured possession? (Source: KakaoPage, translated)
