Stranded on a business trip after his return flight is canceled, a man is approached by a beautiful flight attendant who turns out to be Tsumugi, the quiet married woman from his neighborhood. Speaking properly for the first time, they hit it off thanks to her warm, easygoing personality and end up sharing a room and having drunken sex. They should have stopped after one night, but their chemistry is too good. Repeating the slightly kinky acts he cannot try with his wife whenever he travels, they sink ever deeper into a creampie affair reserved for business trips.
