Sayaka Narimiya, a 28-year-old single woman, has just lost her job at an advertising agency. To make ends meet, she takes up a part-time nude modeling job. However, her past comes back to haunt her when Renji Hasumi, her high school heartbreaker, appears at one of the modeling sessions. As an associate professor, Hasumi is equally surprised to see Sayaka, but instead of rekindling their past romance, he stops her on the street for what seems to be a reunion, leaving Sayaka wondering what his true intentions are.
