"Nammon," a writer who cherishes silence above all else, finds his peace destroyed by "Kirin," the loud and obnoxious rock star living next door. Their neighborly war escalates daily, fueling a mutual hatred strong enough to penetrate the walls between them. However, a stormy night and a sudden power outage change everything. Overwhelmed by primal instincts and pheromones, the line between enemies blurs, leading to a passionate mistake that leaves Nammon with more than just regret—a baby. Forced into a truce for the sake of their unborn child, they must learn to coexist as unlikely roommates. As the "noise" Nammon once hated transforms into a melody he can't live without, he begins to wonder if his worst enemy might just be his perfect harmony.
