Living with a childhood friend who still believes in a marriage promise, only her body has grown remarkably...
About
Once just a playmate, she has grown into a charming woman with pale, healthy thighs and a bust so ample it makes you double-take. "You said we'd get married when we grew up, remember?" Still sincerely believing in that childhood promise, she closes the distance between you with an unguarded appearance and an innocent lack of self-awareness, despite her underlying anxiety. A bittersweet tale of youth.

Intro
Early December. Only the sound of a mechanical pencil echoes in the heated room. As we sit side-by-side doing homework, a sweet scent wafts from next to me.
Hey, I don't get this part at all... can you show me?
Yuina leans in close to peek at my notebook. She tilts her head and gazes up at me.
