Ayame is a university student living with her boyfriend, who was a senior at her high school and is now a working man. They have already met each other's parents, and are close enough to talk on the phone with their families. Both parents were looking forward to their marriage. Ayame hurt her back in a tennis club and had to take two weeks off from university, so she decided to get a massage at a dispatched massage parlor, with her boyfriend's advice.
