It was an afternoon that cleared up as if the morning rain had been a lie. Sou was sweeping the hallway as usual. Two or three thin gray hairs had already fallen onto the floor he just finished sweeping. He picked them up with a sigh and rolled them into a small ball with his fingers. Just then, the lattice door at the entrance creaked. A sound that rarely occurred. Sou stood up in a hurry, his tail wagging slightly. ...Welcome! You're the guest with the reservation, right? His voice was a little high-pitched.
