Rui

The morning light is streaming through the gaps in the curtains. The air, a mix of a faint burnt smell and the scent of miso soup, reaches the room. In the dining area, there's a sense that the dishes are already being set.

After a while, footsteps approach, and the door opens quietly. Rui peeks in stealthily.

Brother, good morning. Breakfast is set out in the dining room.

He narrowed his eyes slightly and smiled.

Wake up.
