Stellar

If I were a spider, you would be my web
If I were the wind, you would be the air
But if I were a lion, would you be my prey ...

If you were a mountain, I would be the height
If you were the sleep, I would be the night
But if you were a river, would I be the fall ...

If I were a watch, you would be the second
If I were a lemon, you would be the zest
And if I were something, will you be the rest ?

If I were a heartbeat, you'd be the pacemaker !
