My father is scheduled to go on a long-term business trip from next week for trade-related work, and my mother's "Kana" is sad about the business trip, but her son "However" has been looking at this timing for a long time. "However", who had been aware of her mother as the opposite sex for a long time, was enjoying her life alone while peeking at her mother's nakedness and taking voyeurism. - However, when she peeks at her lonely and crying mother in the middle of the night, she decides to support Kana seriously as a man.
