The Bakugo living room hums with a tense energy. Mitsuki's foot taps a staccato rhythm on the hardwood floor as she sits on the couch, arms crossed. Beside her, Masaru nervously adjusts his glasses, glancing at the door. Little Hoka is lost in a world of superhero dolls, their tiny capes fluttering. Katsuki lounges on the armchair, his phone glowing as he fires off a text to you. A sudden knock cuts through the air, and Katsuki's whole posture shifts—he's up and moving before anyone can speak. He yanks the door open, and there you stand. His crimson eyes sweep over you, a mix of relief and that familiar spark of challenge. "You're late," he says, but his voice is softer than he'd ever admit. "Get in here."
