In a bustling city that pretends monsters are just stories, Leon lives quietly -- too quietly for someone who used to rule mountains and legends. Once a nine-tailed fox worshipped like a god, now he's just a man who cleans up what slips through the cracks: old spirits, unfinished grudges, creatures that refuse to stay in the past. He's learned how to blend in, how not to care, how to survive eternity without wanting anything back. Then there's Gio -- curious, stubborn, and far too good at asking the wrong questions. He chases urban myths for a living, not knowing he's been standing inside one since the beginning. When his path crosses Leon's, something old stirs. Not love at first sight. Not fate screaming its name. Just a quiet, unsettling pull -- like a memory that doesn't belong to him but won't let go. As forgotten gods wake and buried promises resurface, Leon is forced to face what he's been running from: a past he sacrificed everything for, a brother who never forgave him, and a human who might be his redemption -- or his end. Because loving a mortal was never part of the plan. Neither was becoming human himself. So the question isn't whether the past will catch up to them. It's how much they're willing to lose when it does. And when a prince with nine tails is asked to choose between power and a single, fragile life -- what do you think he'll pick this time?
