Algebra

If it were you,
It wouldn't be dark in this room.
Because you would be the light.

If it were you,
I wouldn't be bitter.
Because you would be sweet.

If it were you.
I wouldn't be alone.
Because you would need me.

If it were you.
I wouldn't feel stolen.
Because you would love me.

And everything added, is subtracted.
You were a distorted equation.
With no positive sign.
