The song is about a girl whose world is destroyed by a change beyond her control.
I think it's a very sad but positive song, it doesn't glorifies the girl's loss, the title implies the girl leaves, she walks away from the place where "all her things are scattered everywhere", her "lucky star" is gone but she didn't sit and watch, crying endlessly, she'll start all over again.
