In a snow-covered village wrapped in silence and mystery, lives Lee Sangwon-a man beloved by all. With his sweet smile, childlike wonder, and endless generosity, he seems incapable of harm. Every day, Sangwon crafts handmade chocolates and hands them out to his neighbors, a simple act of kindness that warms the coldest of winters. But behind his gentle exterior hides something far more sinister. Sangwon is not the innocent soul everyone believes him to be-he is twisted, unhinged, and quietly consumed by obsession. To him, love between others is an unbearable mockery. Couples who flaunt their happiness ignite a dark fury within him. His chocolates, once thought to be gifts of affection, become instruments of death-poisoned delicacies that silently erase every pair who dares to be in love. Each death is followed by Sangwon's secret celebrations, his childish glee masking the horror of his crimes. His ultimate goal: to rid the village of love entirely. As mysterious deaths spread through the village, suspicion grows, and fear lingers in the icy air. To uncover the truth, Detective Lee Leo is sent to investigate. Calm, perceptive, and unyielding, Leo becomes the village's last hope of ending the unseen terror. Yet his presence unsettles Sangwon in ways he does not expect. Though Sangwon fears men and instinctively recoils from them, Leo's quiet determination slowly cracks the walls Sangwon has built around his broken heart. What begins as a hunt for a killer twists into something far more dangerous-an unsettling bond between detective and murderer. As Leo draws closer to the truth, Sangwon finds himself torn between his desire to destroy love and the strange, unfamiliar warmth blooming within him. In a village blanketed by snow and haunted by death, can love truly exist-or will Sangwon's darkness consume it before it has a chance to take root?

Sangwon, a rare hybrid bunny omega with gentle magic and a fragile heart, has spent his entire life running. Hunted for his unique abilities, feared by some and desired by others, Sangwon hides deep within the forest with his brother, Jungwon. Every day, Sangwon looks for food, determined to keep his brother alive despite the danger closing in on all sides. But one day, everything goes wrong. Tracked by a group of elite alphas, Sangwon is chased and captured-not by the hunters they fear, but by a powerful alpha squad led by Leo, intimidating and cold. Sangwon fights, begs, and trembles, terrified of being separated from Jungwon. But Leo refuses to let him go. When Sangwon finally breaks and confesses that his little brother is alone, hungry, and waiting for him, something in Leo shifts. Instead of keeping Sangwon prisoner, Leo makes him a deal: If Sangwon uses his rare hybrid powers to help Leo fight the rising faction that hunts and kills hybrids, Leo will find Jungwon and bring him safely to the headquarters. Desperate to protect the only family he has left, Sangwon agrees. His gentle powers may be the key to ending the conflict-but only if he can learn to control them. Bound by a deal, and haunted by enemies who will stop at nothing, Sangwon must navigate a world of dominance, loyalty, and blooming forbidden desire. And Leo will soon learn that the small bunny he captured might be the one destined to change the fate of their entire world... and his heart.

Lee Leo and Sangwon met as classmates in college, both pursuing Psychology. On the surface, they couldn't be more different-Leo, quiet and withdrawn, keeping the world at arm's length, while Sangwon was curious, openhearted, and drawn to people. When Sangwon noticed Leo always sitting alone, he reached out, determined to befriend him. At first, Leo was difficult to understand-complicated, guarded, a puzzle Sangwon couldn't quite solve. Yet over time, a bond grew between them. Laughter, long conversations, fleeting glances-moments that seemed to hum with something more. For Sangwon, that something blossomed into love. He tried to hide it, fearing it would ruin what they had. But the way Leo looked at him-the spark in his eyes, the warmth in his smile-made it impossible to ignore. For a year, Sangwon treasured every detail, every glance, every heartbeat that made him believe the feeling might be mutual. Finally, he gathered the courage to confess. Leo's response was gentle but devastating. Though touched that he had been someone's happiness, Leo admitted he could not return Sangwon's love-he was straight, and his heart did not sway in that direction. He promised nothing would change between them. But everything did. Days later, Leo began to drift away-ignoring Sangwon, avoiding meals, acting as if their closeness had never existed. Sangwon's heartbreak curdled into anger, betrayal, and bitterness. The friendship that once lit up his life collapsed into silence, leaving only resentment where love had once been. Two years passed. Wounds remained unhealed. Then fate intervened. Their professor assigned them to a joint project-one that required living together for a month, observing each other's habits and daily lives. Forced into close quarters, Sangwon and Leo must confront the wreckage of their friendship, the love that was never returned, and the unspoken truths still lingering between them.
