As long as you love me
---Backstreet Boys
Although loneliness has always been a friend of mine,
I'm leaving my life in your hands.
People say I'm crazy and that I am blind,
risking it all in a glance
How you got me blind is still a mystery.
I can't get you out of my head.
Don't care what is written in your history,
as long as you're here with me.
I don't care who you are,
where you're from, what you did,
as long as you love me.
I don't care who you are.
I don't care what you did.
How you got me blind is still a mystery.
Who you are is not important
What you did made no difference .
