you should dream what you want to dream,
go where you want to go,
be what you want to be,
because you have only one life and one chance to do all the things you dream of, and want to do.

At first you may really get confused as you wouldn't know what the hell is going on...but the story unfolds into a really touching twist....not exactly the typical happy ending which one would expect...and that is what makes it real...
