Nana K. is a hopeless romantic who is co-dependent on everyone around her and falls in love at first sight with any and all men, even married ones; Nana O. is a wannabe rock star who has had to break up with the love of her life so that she can find her own path as a singer. As Nana K. boards a train to Tokyo, she longs to finally be with her beloved boyfriend Shouji; as Nana O. boards the same train to Tokyo, she plans to live her dream with only the guitar on her back. The two meet by chance both on the train and in the city - ultimately choosing to live together - and though they are opposites in every way the girls quickly become close friends. Together, Nana and Nana will learn the bittersweet truth about love, loss, and the growth that comes because of it.
Nana is a little more bitter while Orange is a little sweeter, but I think if you liked one you'd like the other, because both are love stories with sad undertones, again Nana a little more so than Orange. Both include love triangles, conflicting emotions, and lots of regrets, but they both also have happy moments, heartwarming moments.
