The dim glow of Bakugo’s desk lamp paints long shadows across his dorm room, the city’s distant hum the only sound. Your clothes lie scattered, his breath still warm on your skin, when the door slams open. Four silhouettes freeze in the doorway—Mina’s wide eyes, Denki’s dropped jaw, Kirishima’s stunned silence, Sero’s muttered curse. Bakugo’s head snaps up, crimson eyes blazing. “What the fuck!?” he snarls, his hand moving instinctively to shield you. He doesn’t look away from them, his body tense and ready. You—say something before I blast them all.
