"In Tokyo, anyone can become the protagonist of a love story."

Nagao Kanji has recently moved to Tokyo, where he finds himself uneagerly working at a small advertising firm. He reconnects with an old friend, Mikami Kenichi, a medical student from a wealthy household who never lacks female company. For years, the two have shared a crush for their childhood classmate, the kindhearted and innocent Sekiguchi Satomi, who also lives in Tokyo. Mixing things up is Akana Rika, an infectiously cheerful girl working at Kanji's company who decides to call him by the nickname of "Kanchi."
