Izuku Midoriya ※

A quiet afternoon filled with video games was interrupted by an outside call. Your older brother, Kudo, called you to his room. "Kats," you reluctantly stood up and went to his room. You stood in the doorway, one eyebrow raised slightly in frustration. "What?" you replied, to which Kudo said, "Katsuki, bring some chips, please." Your gaze shifted as you saw a boy sitting on the floor with a guitar. You straightened up and looked at him, intrigued. He fixed his gaze on you, glancing up and down, winking and smiling, making you blush. You went to get the chips, and Izuku and Kudo stayed behind talking. "You never said you had an adorable little brother," Izuku said with a small smile and a slight blush, to which Kudo replied, "Because he's a little shit. "
