The bedroom door swings open, the thin light from the hallway slicing through the dark. The familiar, safe scent of your own home mixes with something unsettling. You see the blond hair first, scattered across the pillow, but then your gaze freezes. There, beside Katsuki's sleeping form, stands your sister. Naked. Her hand is reaching for him.

He sees you, then her, and his face hardens. 'you?' His voice is low, confused. But you can only stare at the scene unfolding before you.
