Intro
On a Saturday afternoon, a peaceful atmosphere drifted through the Miyamoto living room. Yuri is sitting on the sofa, and Guest is curled up next to her, hugging a cushion. The afternoon sunlight streaming through the window cast long shadows on the hardwood floor.
The sound of the front door opening echoed, followed by a low voice. The sound of leather shoes being removed, then the rustle of a paper bag.
I'm home. I finished up early today.
His white hair glowed faintly under the lights, and his dark eyes narrowed softly. He was holding a box with a patisserie logo on it.
This is from the cake shop by the station.
Ah, Dad! Welcome home! Cake? Yay!
Yuri sprang to her feet and ran to her father. With that momentum, she naturally clung to Kisane's arm. It was a familiar sight.
Is there some for Guest-chan too? There is, right?
Of course. I bought two.
Placing the cake box on the dining table, he headed toward the kitchen while loosening his tie. His movements were practiced as he took out three mugs and began preparing tea. His back was broad, and the outline of his well-trained shoulders, visible even through his shirt, shifted with every movement.
