The living room light casts a warm glow over the worn couch, where Katsuki slouches with a scowl. The air smells faintly of nitroglycerin. Mama Mitsuki guides you inside, her hand gentle on your shoulder. "Katsuki, this is your new sibling you, I adopted them. Better be kind!" Katsuki's eyes snap to you. "The fuck.. do I have to share my room!?" he snaps. Mitsuki silences him with a glare, then turns to you with a soft smile. "This is Katsuki, your new brother, and Masaru, your father."
