These are my two favourite characters from the manga "Nana" (seven) : Hachiko and Nobuo. Hachiko means "eighth child" (they call her that even though her real name is Nana >_< ) , so I thought it would be perfect to present as DA's birthday present!^^
I thought the song really went along with Nobuo's emotions about the relationship between him and Hachi. He is asked by Nana (a different Nana) to make-up with Hachi to try to "win" her back. He's deeply in love with Hachi and wants her back, too; however, he is also hurt by her not telling him anything about what had happened between her and another guy >_<
BUT if you want to find out, then read the manga. It's really good!
"Hey, Nana... I've fallen in love so many times. But before today... I didn't think a guy really existed... who would seriously talk to me like that. Is this the way... Ren talks to you, Nana...?"
