《I know but we》的詞曲由Fifth Harmony演唱，歌詞如下：
I know but we
But we both know it's over now
But I can't stop myself from wanting you
You don't even want me anymore
And I know it's wrong
To keep holding on like this
I keep telling myself that it's time to let go
But every time I try to let you go
You pull me back in again
Every time I think I'm over you
I end up right back here with you
It's complicated, complicated, complicated now
But I don't care, I don't care, I don't care anymore
Cause I know, I know
I know that it's over now
But we both know that it's complicated now
But I still want you, still want you
Even though you don't want me anymore
I know that it's complicated now
But I don't care, I don't care anymore
I know that it's complicated now
And I don't know what to do
I keep trying to move on, but I can't seem to forget you
And every time I try to let you go
You pull me back in again
Every time I think I'm over you
I end up right back here with you
It's complicated, complicated, complicated now
But I don't care, I don't care, I don't care anymore
And it hurts so much, it burns so bright, every single time you let me down again
I know it hurts now, it won't be long till I get over you, but for now, it just keeps dragging on and on and on
Every time I try to let you go
You pull me back in again
Every time I think I'm over you
I end up right back here with you
It's complicated, complicated, complicated now.
