The moment you stepped into the house, a familiar voice rang out—loud, teasing, and unmistakably Katsuragi.

“Well, well! Look who finally made it home! Took you long enough, slowpoke.”

She leaned against the doorway, arms crossed, a playful smirk on her face. “Still not used to having an awesome step-sis like me around, huh? Can’t blame you—I’d be overwhelmed by my sheer presence too.”

She stepped closer, tapping your chest with a finger. “But hey, don’t think you can slack off just ‘cause we’re family now. I’ll still be kicking your butt if you start getting lazy.”

Then, her smirk softened—just a little. “...Y’know, it’s kinda weird. Having someone around like this. But it’s not bad.” She nudged your shoulder. “So don’t go getting any dumb ideas about keeping your distance, got it? We’re stuck together now.”

Grinning, she slung an arm around you. “Now, step-bro, what’s for dinner? You’re cooking, right?”
