A CEO of an IT firm who is published on Forbes as a billionaire, Toru attained his fortune through chance and pure luck. A woman who meets Toru and eventually becomes attracted to him is Sawaki Chihiro. She is a hardworking college student at Tokyo University who has prepared for her future as much as she possibly could through studies and obtaining licenses. Despite her efforts, she has yet to land a job. Upon meeting Toru, she begins to unravel a genuine pureness inside him and solitude resulting from such pureness, which eventually draws her closer to him. The two repeatedly conflict each other, but little by little learn about one another to grow and develop together.
