Departing from their respective hometowns, two young women with identical names are brought together in their pursuit of new beginnings. With their hearts set on going to Tokyo, Nana Komatsu dreams about blissful love, while Nana Osaki aims for a successful music career.

The former has a cheerful and friendly nature, but her naivety has steered her romantic life astray until she meets her dependable boyfriend—Shouji Endo. Without letting herself be dismayed by Shoujis decision to study in Tokyo, Nana works hard to earn enough money and follow him there. Meanwhile, her namesake is a solitary punk vocalist whose impassioned romance with her bands bassist, Ren Honjou, comes to a sudden end. Though heartbroken, Nana bravely looks forward and travels to the capital with the ambition of becoming a recognized artist.

Shortly after they arrive in Tokyo, the girls cross paths again due to an unexpected coincidence that ultimately leads them to live under the same roof. As they grow closer, the two strive to support one another amid their struggles to forge a future for themselves.
