다음 중:Yoshino, who recently moved into his own room, falls asleep in his room every day. One day, I looked out the window and saw my neighbor Yuka hanging clothes to dry. Yoshino was fascinated by that moment. Watching Yuka wash clothes every day has become a daily routine, but she has always been worried that the sheets being washed will be unnaturally stained. .
