Ten years ago, a girl at the age of nine step foot on the ground of L.A., U.S.A during December's winter.
She told herself, "This is the place where I want to be. I may not know why. But I will be back. It will only be a matter of time."

Ten years later, this same girl still has the same desire of going back to U.S.A.
Still not knowing the reason why.
But the promise she made to herself, will be fulfilled...
It will only be a matter of time.
