A widow surrounded by younger men

A few years after she moved to the countryside with her husband, Isao, who worked as a teacher until his retirement, Isao passed away due to illness. Yuuko is overwhelmed with grief, but today a student from the track and field club where her husband was an advisor before his death came from Tokyo to give her incense sticks. Yuko was able to forget her sadness for a while when she met her husband's students who had all grown up for the first time in several years, but... However, Yuko, who let her students stay at her house that night, comes to know that that decision was a mistake.
