this can be about anything or anyone.

I don’t care how long it takes I will wait for you.
if I'm done with what I have now and you're not there, I’ll still be happy to know that you exist and you changed my life and now I can live a different way. your ideas change me, your life changes me, I already know I love you, you can make me dream again, and I know I love you. I loved you before I knew you.
