She.

She may be the face I can't forgetThe trace of pleasure or regretMay be my treasure or the price I have to payShe may be the song the summer singsMay be the chill the autumn bringsMay be a hundred different thingsWithin the measure of a day
She may be the beauty or the beastMay be the famine or the feastMay turn each day into a heaven or a hellShe may be the mirror of my dreamsThe smile reflected in a streamShe may not be what she may seem inside her shell
