The snow glows white on the mountain tonight.
a footprint to be seen;A kingdom of isolation;And it looks like I’m the queen;The wind is howling like this swirling storm ;
keep it in, heaven knows I’ve tried;
let them in, let them see;
the good girl you always have to be;Conceal, feel, let them know;Well, now they know;
it go, it go;
hold it back anymore;
it go, it go;
away and slam the door;
I don’t care what they’re going to say. the storm rage on;
My power flurries through the air into the ground;
My soul is spiraling in frozen fractals all around.
And one thought crystallized like an icy blast;
I’ m never going back, the past is in the past;
it go, it go.
And I’ll rise like the break of dawn;
it go, it go.
That perfect girl is gone;
Here I stand in the light of day;
the storm rage on;
The cold never bothered me anyway.
