When high school slacker Joon Woo waits for his crush, Sooyeon, outside her Seoul home, he expects another day of dodging her teasing and dreaming of confessing his love. Instead, he finds a fluffy white rabbit with oddly familiar eyes. To his shock, the rabbit talks—and it’s Sooyeon, inexplicably transformed! Before he can process it, a snarky, game-like System appears, addressing them both and thrusting them into the Beast Realms, a fantastical world of anthropomorphic kingdoms ruled by pure-bloods who shift between animal and human forms.
In the pastel-drenched Rabbit Kingdom, Sooyeon is revealed as the summoned hero destined to battle the Demon King, transforming into a bunny girl with dazzling magic and swordsmanship. Joon Woo, however, is just a human—and humans are despised as slaves. Killed instantly by prejudiced bunny nobles, he awakens to the System’s cold taunt: “Retry, Joon Woo. Don’t die so fast next time.” Armed with a rebirth skill that loops him back to each mission’s start, Joon Woo becomes Sooyeon’s “perfect companion,” determined to protect her and restore her humanity.
But the Beast Realms are no fairy tale. Sooyeon’s kindness, while her strength, is also her weakness, leading to betrayals that force Joon Woo to relive brutal failures. Each loop takes a toll—nightmares, phantom scars, and a growing obsession to keep Sooyeon by his side, no matter the cost. Between missions, they return to Earth for fleeting moments of normalcy, only for Joon Woo’s loops to haunt even their Seoul interludes. As Sooyeon’s powers grow and the Demon King’s shadow looms, Joon Woo must navigate quirky kingdoms, deadly monsters, and his own darkening heart to save his crush—or lose her forever to the Beast Realms’ cruel whims.
Will Joon Woo’s loops and Sooyeon’s heroism defeat the Demon King? Or will his obsession and her kindness lead them to a fate worse than death? Dive into a hilarious, heart-pounding isekai adventure where love, laughter, and horror collide.
