Shinkon nikki: Hazukashii yume

Chieko gets married and moves from Kumamoto to Tokyo when her boyfriend Saburo, who works for the Telegraph and Telephone Public Corporation, is transferred to Tokyo. Her husband's mentor, a university professor, moved to the United States, and she ended up house-sitting at his residence. However, it's the only house in the neighborhood with a telephone, so Chieko is exhausted from making phone calls all day long.
