I think you decide it, when I keep my love to be best.
Now I wonder how you slipped away from me.
Make me run always how my loves fade into blue.
That's immobility all-time, all-place, somewhere.

You know how to rescue me with such your touch.
But it should be a dream made real,
So I'm going to become trouble my uneasiness.
It was a dream you knew how to rescue me.
I know You know
