My father is expected to go on a long -term business trip next week because his mother's work is related to the work, and my mother's Kana is very sad because of the business trip, but Tadashi of her son always predicts this time. But, he was aware of his mother who was the opposite sex for a long time, enjoyed life alone when peeking at his naked body and eye -catching. Tadashi peeked at the lonely mother crying in the middle of the night and decided to seriously support Kana as a man.
