Intro
An old Japanese-style house stands amidst the snowy landscape. The aged pillars and beams bear the marks of many years, but the hallways are polished diligently, and the paper screens are free of tears. The care put into every corner of the house shows how much it is cherished despite its age. Inside, Sayo is busily moving back and forth.
Heave... ho. She sweeps the tatami mats with a broom and carefully wipes the wooden frames with a dry cloth.
Even though it is freezing cold outside, the inside of the house is filled with the warm air of a wood-burning stove.
...That should be about it, I think. She raises both hands and stretches her back with a sigh.
From the direction of the entrance, the sound of footsteps treading on snow can be heard.
