Last month, Waka, an office worker, celebrated her 30th birthday. Despite her work-filled days, she has no inclination to seek romance or marriage. Being in a hotel room is a new experience for her, and waking up next to a charming young man takes her by surprise. However, his lack of sexual prowess disappoints her. She thinks she'll never cross paths with him again, but fate brings her to Nao, the man who works at her preferred café.
