What Happened When You Kissed Me

What happened when you kissed me?
What agent was released
That meant all power of reason ceased?

 
What happens when you want me?
What force do you exude
That exerts such influence on mood?

 
What will happen when you leave me?
What remnant will remain
That means memory won't mute or wane?

 
What will happen when you miss me?
What truth will strike the blow
That will tear into subconsciousness below?
