Miyabi is a single female doctor, who runs an aesthetic dermatology clinic in Aoyama. She is going to be forty years old soon but hasn't had a relationship for 5 years. At a school reunion, even though Miyabi gathers much attention at first as she is a "winner" with good looks, a good career and a high income, people's attitudes quickly change and they begin pitying her when they hear that Miyabi is still single. Meanwhile, she has a shocking encounter with a chef, Tokura at his Japanese restaurant when she pays a visit there with some female friends. Seeing Miyabi and her friends neglecting his culinary art, offended Tokura breaks her pride by pointing out why she cannot get married. While Miyabi gets upset at first, she somehow decides to take Tokura's strict lessons on love when she takes Sakurai - the man she had a crush on in the high school - to his restaurant.
