[Verse 1]
Summer's end, September first
Said I could keep your killer shirt
But wearing it just makes it worse, yeah
Wasn't sure if it was love
But now I know it really was
And thinking 'bout it hurts so much, yeah

[Chorus]
Cause I just can't forget you
I just can't forget you
I just can't forget
I know it's over, I'm just not over it

[Verse 2]
I know he means it when we kiss
He doesn't do it like you did
And I feel bad for thinking it, yeah
All my friends say he's nice
He tries his best and treats me right
But you still keep me up at night, yeah

[Chorus]
Cause I just can't forget you
I just can't forget you
I just can't forget
I know it's over, I'm just not over it
Can't forget you
I just can't forget you
I just can't forget
I know it's over, I'm just not over it
[Bridge]
How could I have known
Your love will never grow old
Your love will never grow old
How could I have known
Your love will never grow old

[Chorus]
Cause I just can't forget you
I just can't forget you
I just can't forget
I know it's over, I'm just not over it
Can't forget you
I just can't forget you
I just can't forget
I know it's over, I'm just not over it
