A still-single 40-year-old Nakahara Aki has a successful career but struggles when it comes to love. She appears to be an attractive, independent and capable woman, but whenever she starts going out with a guy, she tries too hard and often ends up miserable. After experiencing a series of disastrous relationships, Aki is now fearful of falling in love.

Aki has two best friends she often gets together for a girl talk: Osaki Moeko an owner of a flower shop, and Sakata Midori, a divorced working mother raising three boys on her own.

At work, Aki has been put in charge of developing a role-playing romance game app with a group of team members who are all younger than Aki. One day, Aki approaches a scriptwriter famous for romantic dramas, Takayama Fumio, and asks him to be the supervisor/advisor for the game app development project. At their first meeting, the two get into an argument when Fumio makes a comment about being 40 and still being infatuated with crush-like romance...
