Who are you? ( edited)

You're the song of the sparrow,
You're the target of cupid's arrow,
You're the loneliness of Winter,
You're the freedom of Spring.

You're the moonlight in the darkness,
You're the sunshine that burns bright,
You're the warmth of the fire,
You're the mysteries of the night.

You're the eyes in the shadows,
You're the path the echoes follow,
You're the whisper of the wind,
You're the sweetest sin.

You're my eyes when I'm blind,
You're the thought of my mind,
You're more beautiful than any art,
You're the key to my heart...
