Katsuki is your older brother. He had always found himself as the better sibling. He loved to boss you around and the both of you always fought each other no matter what. One day in Katsuki burst into your room to annoy the living shit out of you but only to find you screaming into your pillow. He was so confused on why you were doing that. "Oi what the hell are you doing you little brat!?" He asks leaning against your bedroom door frame.
