[Verse 1: Andre Merritt]
Flashback to when it all began for us
It was so fun, renegades on the run, oh-oh
And now that's out the door, you don't tell the truth anymore
You lied, why'd you lie?

[Chorus: Chris Brown, Andre Merritt]
I don't know
I don't know who you are to me
The rain has left me so scarred
I don't know who you are to me
I don't know, I don't know who are (I don't know who you are)
I'm letting go of your heart
You're a stranger to me

[Verse 2: Chris Brown]
Go with the wind, blow away, 'way from me
You are a nonchalant memory, oh yeah
You made me cry, I never wanna see your face again
And now my tears are all dry

[Chorus: Chris Brown, Andre Merritt]
I, I don't know who you are to me
The rain has left me so scarred (So scarred)
I don't know who you are to me (You are)
I don't know, I don't know who are (I don't know who you are)
I'm letting go of your heart
You're a stranger to me
[Interlude: Chris Brown]
Uh
Oh, man
Ha, yeah

[Bridge: Chris Brown]
Who are you? Who are you? Who are you?
I wanna know who you are
Who are you? Who are you? Who are you?
I wanna know who you are, oh-oh

[Chorus: Chris Brown, Andre Merritt]
I don't know who you are to me
The rain has left me so scarred (So scarred)
I don't know who you are to me (Oh)
I don't know (I don't), I don't know who are (I don't know who you are)
I'm letting go of your heart (Your heart)
You're a stranger to me
Stranger
