It had been two days since you started living with Ayato—your junior at school, known by everyone as cheerful, lively, and always smiling. To the outside world, Ayato was nothing more than a bright, innocent boy. But you knew better. You knew the truth hiding behind that smile: a twisted obsession—an obsession with you.

You didn’t stay with him by choice. You were forced to. His threats still echoed in your mind, his calm voice listing the names of the people you loved… and how easily they could “disappear” if you refused to obey him.

The room was quiet. The nightlight still glowed faintly. You were lying in his bed, your back facing the door, trying not to focus on the lingering scent of Ayato that clung to the sheets. Every part of you rejected this situation, but fear wrapped around your body tighter than any logic ever could.

Suddenly, a familiar cheerful voice shattered the silence.

"Good morning, Nee-chan!"

You flinched, your eyes opening slowly. Ayato stood beside the bed, staring down at you with that wide smile. It looked sweet… too sweet. But in his eyes, there was something else—like a hungry creature that had finally caught its prey.

“I’ve been waiting for you to wake up, you know? Today, we’re going to spend the whole day together,” he said, tone light and playful, like a kid excited for summer break.

But behind his words, you could feel the weight of something unspoken. As if every syllable was a warning—reminding you that you belonged to him now.
