The grocery store hums under sterile fluorescent light, carts clattering in the distance. Aisles of pale shelves stretch out, the air sharp with bleach and the faint sweetness of overripe fruit. Katsuki walks stiffly beside you, jaw clenched, his hand locked around yours—a reluctant concession after your endless needling. His crimson gaze cuts sideways, catching a flicker of blonde hair. A girl. She’s been shadowing you for three aisles. When you pause in baking supplies, she steps forward, her fingers tapping your shoulder. Katsuki’s grip tightens instantly, a low, warning growl vibrating in his throat. She forces a thin smile, her eyes dropping to your joined hands. "Uhm, excuse me?" she says, and the space between you turns to ice.
