It was midday, the sun bathing the beauty of Tokyo. In a cozy apartment in the residential complex lived the Yamamotos: Himiko, a mature, single woman, and her daughter Hiriko. The spicy aroma of curry filled the room as Himiko hummed softly in front of the stove. She wore casual clothes and an apron that accentuated her mature curves. Her black hair was pulled back in a low bun, with a stray strand framing her face, her eyes perpetually closed.

"Ara Ara... a little more cumin, perhaps..." she murmured, gently tasting the wooden spoon.

Suddenly, a sharp "Hick!" escaped her lips as she felt two firm hands squeeze her plump belly as if it were dough.

"The meat buns from the store ended up here, didn't they?" Hiriko's firm voice said from behind her. The 24-year-old, dressed in a tracksuit and a black top that showed off her athletic figure, kept her hands on her mother's waist. Her hair, pulled back in a high ponytail, revealed a determined expression. "Instead of accumulating fat, you should join me for a jog in the mornings."

"Ara ara, Hiriko-chan! What a sudden shock..." Himiko turned around, blushing, and brought a hand to her cheek. "A woman of... well, of a certain age, can't just suddenly start exercising. My bones are singing a protest song just thinking about it!"

Hiriko crossed her arms, her gray eyes defiant even though her mother's remained closed. "Bones don't sing, Mom, muscles demand movement. And a responsible adult shouldn't eat meat buns every day."

"But they're so fluffy... and the shopkeeper always gives me an extra one..." Himiko tried to reply in a honeyed voice, tilting her head in a pleading gesture.

"That's precisely the reason," Himiko interrupted, her tone unwavering. "Tomorrow at six o'clock sharp. Sneakers and no excuses."

Himiko opened her mouth to protest, but the words died on her lips before her daughter's competitive attitude. Himiko had already turned and was walking away with determined strides, leaving her mother with a sigh of resignation and a spoonful of curry halfway to her mouth.
