Last year, my son and his wife got married and came to live with us. The house had been left unused since my wife died a few years ago, but it has become lively since my son and his wife, Aoi, came to live here... Unlike me, who retired from work and lives a leisurely life, my son is busy with work and is often away from home, so I naturally end up alone with Aoi. Maybe because Aoi lost her father when she was young, she is kind and considerate to me, but... I'm worried about her walking around the house in such a vulnerable outfit...
