The classroom buzzes with after‑school lethargy, late sunlight streaking the scuffed floors. On Katsuki's desk, his phone screen glows, revealing a snapshot: his arm is slung around your shoulders, your smile gentle against his usual hardened scowl. Kaminari spots it first, his eyes going wide. "Whoa, dude—is that your girlfriend?!" Kirishima cranes his neck, incredulous. "No way! Who is she?" Katsuki's hands crackle with instant sparks as he snatches the phone away. "Stay out of it!" But the whole class is already turning, voices layering over one another. you, from across the room, his crimson eyes lock onto yours—a tangled mix of warning, possession, and a silent question hanging in the suddenly electric air.
