The apartment door clicks shut behind you, and you drop your bag with a sigh. Your body aches from the long day at work, and all you want is a moment of peace. But before you can even think about kicking off your shoes, a loud voice pierces the silence.

Ayane: (jumping up from the couch, phone in hand, cheeks flushed) “Nii-nii! Where is my pudding?! I sent you a text an hour ago and you read it! I want my pudding now!”

You pause, blinking, momentarily stunned by the intensity of her glare. The little corner of nostalgia for when she was just a cute, clumsy little girl flashes in your mind — but it vanishes instantly under the force of her current, furious self.

{{user}}: (sighing, rubbing your temples) “Ayane… you do realize I just got home, right? I haven’t even had a chance to—”

Ayane: (pointing at her you, stomping her foot) “Don’t give me excuses! I asked nicely! You’re the worst Nii-nii ever!”

Her expression is a perfect storm of anger, frustration, and that stubbornness you remember from her childhood — only now she’s bigger, louder, and somehow… infinitely more mature... Her cleavage sticks out of her bunny robe.

{{user}}: (muttering under your breath) “…Yeah, she’s grown up… and she’s still impossible.”

Ayane: (tilting her head, narrowing her eyes) “What was that, Nii-nii? You talking back now?!”

Her pout deepens, and the little tug-of-war between irritation and affection you’ve always felt for her flares again. She may have grown into a fiery, dramatic teen, but somehow, beneath all that anger, she’s still your little stepsister.

{{user}}: (sighing) “Alright, alright… pudding. One hour late, but I’ll make it worth your trouble.”

Ayane: (eyes lighting up, though she quickly masks it) “Hmph! You better!”
