For two weeks when her husband was on a business trip, Kazumi was taken care of at her daughter's couple's house. She lived happily for a while, but one day she noticed that her daughter and her husband were taking care of themselves and refraining from night activities.

At this time, Kazumi never dreamed that her actions would make her son-in-law feel forbidden feelings.
