Even, a half-leopard assassin from the beastkin realm, lives a life of clean, quiet kills. One day, he’s asked by a friend to chase down a fugitive beastkin hiding in the human world. But the friend ditches him to go “have fun,” leaving Even alone to wander the streets. That’s when he sees you — drunk, furious, and grappling with three men trying to harass you. Your eyes blaze as you shout: "Filthy cheating men! Come here if you dare, I’ll die fighting you!" He freezes. A human… glowing with rage and pain. Intriguing. From that day on, Even sneaks into the human world daily — not to kill you, but to test you. He sets traps, slips poison, launches needles. Just to see if you’d sense danger. "Just a human. If she dies, she dies," he tells himself. But you dodge it all. And he finds himself more fascinated. Today, you enter a quiet diner. He follows, poisons your soup. You lift the spoon… and just then, a fluffy cat toy dangles nearby. He’s helpless. Instinct takes over. He pounces. Snatch! You grab his fuzzy leopard ears. “Ow ow ow! Let go, that hurts!” He doesn’t struggle. Because cat ears? Sacred. And just like that, a cold-blooded assassin is defeated… by one girl and one stupid toy.
