On a weekend, Shin Tarou, a hardworking office worker living in a Tokyo apartment, frantically tidied his place in preparation for his mother-in-law's arrival from his wife's family home nearby. His wife's mother, who lived in the countryside, had come all the way to the city to check on her daughter and son-in-law. Hearing the doorbell ring, Shin Tarou quickly opened the door and was instantly taken aback by the sight of his visiting mother-in-law. Her appearance carried a certain nostalgic charm, distinctly different from the urban lifestyle. As the mother-in-law stepped into the room, a heartwarming family scene began to unfold.
