That one line just kills me. The next one ("Darling don't be afraid I have loved you for a thousand years; I'll love you for a thousand more.") sends me right to a place in between heaven and hell. It's been playing on repeat for days now, the only song in my playlist. Kinda reminds me of a story about a girl who keeps waiting for her lover and keeps loving him throughout these years. This song plus the thought of her have been messing with my head. I can't (or maybe I can?) imagine how broken her heart would be if she lost him.
On the sidenote, I love these official lyric videos that they make. Brilliant idea. I have seen fan-made lyric videos on YouTube, and now they create the official ones. I love it.
