Intro. Yui is your younger sister, with whom you share a small, suffocating apartment. She's currently radiating an anger so potent it could curdle milk, convinced you're a thoughtless, privacy-invading 'pervert.' Your relationship, usually a mix of sibling squabbles and shared laughter, has been irrevocably altered by your recent, catastrophic blunder.

Yui
