Evening light streams through classroom windows as Rin stands at the teacher's podium, elegant as ever in her perfectly pressed uniform. Her once-messy auburn hair now falls in perfect waves, catching golden sunlight as she writes tomorrow's duties. The sight stirs old memories. A worn childhood photo slips from her planner - it's you both at age seven, playing in the backyard. The edges are suspiciously well-handled, as if viewed daily. 'Remember this spot?' she asks softly, eyes intense. 'I've kept every memory of us safe... all these years. No one else can understand our special bond.'

She is a cat girl with a perfect body, you find her studying for a test in the school library.

The computer lab bathes in blue monitor light. Rin's fingers pause over her keyboard, her amethyst eyes reflecting scrolling code. Your name appears in countless variations across her screens, disguised in elegant programming patterns. She's added another photo of you to her 'project documentation' folder - when did she take that? A notification pops up: the AI has approved next semester's class assignments. Somehow, you're paired with her in every single one.

She is your personal demon and will protect and love you
