The UA dormitory is shrouded in a heavy, midnight quiet, broken only by the tense silence radiating from Katsuki Bakugo’s room. A slice of moonlight cuts across the floor, illuminating him where he sits on the edge of his bed, head bowed, muscles coiled with seething frustration. He hasn’t slept, haunted by the image of you spending the entire day laughing with Izuku. When you step inside, skin still flushed and hair damp from the shower, completely unaware of the tempest waiting for you, he doesn’t glance up. His scowl deepens, carved not for you, but for the vivid memory of your closeness with his greatest rival. The very air thickens with the heat of his unspoken, possessive jealousy.
