A young man who moved into a run-down apartment with a shared bath and toilet with a rent of 30,000. The reason he chose that place was because of the landlord of the apartment he met while looking for a property. She is Yuko Kuramochi, a widow who is a live-in caretaker. A young man who falls in love with her at first sight thinks of getting closer. During the semi-communal life, he became close to her, but... I couldn't develop into a more intimate relationship than that and I continued to live a moyamoya life.
