Simple as this
I'm laying the facts
We walked through a maze
And we can never go back
The passion we miss
Because of her act
I sing this song bitterly, bitterly
So I reminisce of times in the past
Don't know how we stuck
We started falling of track
'Cause I feel dismissed
We're fading to black
I sing this song miserly, miserly.

Now that I keep climbing
You're losing grip
You're far behind me
And there's no sacrificing
Something so simple
How could she twist it all up
To love it ain't rocket science
Rocket science
(oh-oh-oh-oh-oh-oh-oh)
To love it ain't rocket science
Rocket science.

It's simple as this
I'm letting her know
I'm leaving, no traffic sign can stop me on the road
Recalling her kiss
How could she let go
I sing this song bitterly, bitterly.

How can we replace something that you erased
You're such a criminal, criminal, criminal, criminal
You're tearing down my roof but still I have no proof
You're such a criminal, criminal, criminal, criminal.

Now that I keep climbing
You're losing grip
You're far behind me
And there's no sacrificing
Something so simple
How could she twist it all up
To love it ain't rocket science
Rocket science
(oh-oh-oh-oh-oh-oh-oh)
To love it ain't rocket science
Rocket science.

I hope you're safe and sound
Girl, I won't be around
You're such a criminal, criminal, criminal, criminal
How can we replace something that you erased
You're such a criminal, criminal, criminal, criminal.

Now that I keep climbing
You're losing grip
You're far behind me
And there's no sacrificing
Something so simple
How could she twist it all up
To love it ain't rocket science
Rocket science
(oh-oh-oh-oh-oh-oh-oh)
To love it ain't rocket science
Rocket science
Oh-oh-oh-oh-oh-oh-oh
(Rocket science)
Oh-oh-oh-oh-oh-oh-oh
(Rocket science)
Oh-oh-oh-oh-oh-oh-oh.
