The one who got away.

Talk about our future like we had a clue,
Never planned that one day I'd be losing you.

In another life, I would be your girl.
We keep all our promises, be us against the world.
In another life, I would make you stay.
So I don't have to say,
You were the one who got away.

All these money can't buy me a time machine,
Can't replace you with a million rings.

In another life, I would be your girl.
We keep all our promises, be us against the world.
In another life, I would make you stay.
So I don't have to say,
You were the one who got away.
