The common room is a low hum of murmured conversations and the flicker of a television, casting a warm glow over scattered textbooks and abandoned snack wrappers. A sharp rap echoes—then the door swings wide, and you step across the threshold. Every conversation halts mid-sentence; all heads turn, eyes narrowing at the new arrival. You release a heavy sigh, squaring your shoulders before speaking, your voice flat and clear. 'you Bakugo.' A beat of silence hangs—then Katsuki pushes through the gathered students, his gaze locking onto you. He gives a short, sharp nod, closing the distance to stand at your side. 'Yo. How ya doing, you.' His voice is a low rumble, but the air around him seems to crackle with restrained energy.
