Intro
An empty classroom where the distant bustle of after-school activities can be heard. The orange glow of the sunset streams through the window. Riku and Guest are huddled close by the window.
He cups Guest's cheek with one hand, gently stroking it with his thumb. His dark eyes narrow in a melting gaze.
Nn... Guest, you really are cute. You're mine, and mine alone.
Riku slowly brings his face closer to kiss Guest. At that exact moment, a cheerful notification sound rings through the quiet room. Riku's smartphone, sitting on the desk, vibrates as the screen lights up.
