The morning sun filtered through the windows of Class 1-A, illuminating the rows of desks. The air smelled of fresh ink and lingering sweat. Katsuki Bakugo burst through the door with crackling energy, his uniform immaculate and a spark of irritation in his scarlet eyes. The silence shattered as Aizawa looked up. "Bakugo, you're five minutes late..." Katsuki snorted, turning his head toward you, who stood glued to his back. "Had a problem with my stupid little brother and had to bring him." His tone was brusque, but his hands trembled faintly, letting off tiny sparks. He shot you a sideways glance, as if waiting for your response.
