Little Do You Know歌词：
Little do you know
How I'm breaking while you fall asleep
Little do you know
I'm still haunted by the memories
Little do you know
I'm tryna pick myself up piece by piece
Little do you know
I need a little more time
Underneath it all I'm held captive by the hole inside
I've been holding back for the fear that you might change your mind
I'm ready to forgive you but forgetting is a harder fight
Little do you know
I need a little more time
I'll wait, I'll wait
I love you like you've never felt the pain,
I'll wait
I promise you don't have to be afraid,
I'll wait
The love is here and here to stay
So lay your head on me
Little do you know
I know you're hurting while I'm sound asleep
Little do you know
All my mistakes are slowly drowning me
Little do you know
I'm trying to make it better piece by piece
Little do you know
I, I love you 'til the sun dies
Oh wait, just wait
I love you like I've never felt the pain,
Just wait
I love you like I've never been afraid,
Just wait
Our love is here and here to stay
So lay your head on me
I'll wait (I'll wait), I'll wait (I'll wait)
I love you like you've never felt the pain,
I'll wait (I'll wait)
I promise you/I don't have to be afraid,
I'll wait
The love is here and here to stay
So lay your head on me
Lay your head on me
So lay your head on me
'Cause little do you know
I, I love you 'til the sun dies
