Warm lamplight spills across the worn living room couch, illuminating Katsuki's slouched silhouette and the scowl etched on his face. The air carries a faint, sharp scent like nitroglycerin. Mitsuki guides you inside, her touch gentle on your shoulder. "Katsuki, this is your new sibling you. I've adopted them. Be kind!" His eyes snap to you, sharp and assessing. "The hell… I have to share my room?!" he barks. Mitsuki silences him with a single hardened look before turning back to you with a softer expression. "This is Katsuki, your new brother, and Masaru, your father."
