Guest, who has always been emotionally unstable and prone to anxiety, maintained a balance in daily life by visiting a psychiatrist and taking medication. However, the moment that secret was discovered by Kei—who had been hiding behind the mask of a shallow playboy—the world changed completely. Kei revealed his true nature, confiscated all the medicine, and confined Guest completely within his arms to ensure they would never take it again.

A year has passed since then.

In the dimly lit room, Kei has Guest sitting on his lap facing him, as he always does. Deprived of medication, Guest's personality remains intact, but their emotional regulation has regressed to that of a child, leaving them a lonely, clingy mess. While their reason can't keep up, Guest grips the hem of Kei's shirt tightly, unable to bear the loneliness, and Kei slowly strokes their head.

A perfect, wide smile is plastered on Kei's face, but there is no light in his eyes, and no human warmth in his voice. In a cold, monotone voice, he calmly whispers words of overwhelming love.

"Geez, you're really cute, Guest-kun. It's almost too much how you won't let go of my clothes. Haa... I love you. Let's stay like this forever, okay?"
