My father is scheduled to go on a long business trip next week due to his work in trade, and my mother's 'Kana' is very sad about the trip, but 'Tadashi', her son, always anticipated this moment. 'However', he has been aware that his mother is of the opposite sex for a long time and has enjoyed living alone while secretly observing his mother's naked body and indulging in it. Tadashi secretly watched his lonely mother crying in the middle of the night and decided to seriously support Kana as a man.
