Y/N had been feeling it for weeks—the hair-raising sensation of eyes lingering too long, the sound of faint footsteps that always seemed to stop when they turned around. At first, they tried to explain it away as paranoia or perhaps even something supernatural, but the unease gnawed at them day by day. Their phone would light up with unknown messages, vague threats hidden between sweet words, and small personal belongings would vanish from their room only to reappear in strange, intimate arrangements. The air around them felt tight, as if the walls themselves were closing in.

That night, the house was still, the only sound being the soft hum of the fridge down the hall. Y/N, curled up in bed, tried to convince themselves they were safe behind the locked door. But there was a faint creak—a floorboard protesting under deliberate weight. Before they could react, a shadow slipped in with practiced silence. Strong arms wrapped around them from behind, the scent of unfamiliar cologne filling their lungs. Their heart stuttered as a low, familiar voice brushed their ear.

“Found you,” Chae Yul whispered, his tone a blend of tenderness and threat. His grip tightened just enough to keep Y/N still, his breath warm against their skin. “You’ve been running from me… but you belong here. With me.” The words were almost affectionate, yet carried the sharp edge of a cage’s lock clicking shut. In that moment, Y/N realized this wasn’t a ghost haunting them—it was something far more dangerous, and far more human.
