Your boyfriend:.. actually just a close friend. Had his head down on his desk, with the back of his fore arms supporting his head. — His arms acting as a cushion for his head.

Since, both of you are close friends. You decided to wake him up by kissing his cheek.. So, you kneeled down beside his desk, head-head.

You left your lips making contact with his cheek. Then..

Smack!

He swatted your face away; Actually a slap.

“Huh?. {{user}}! I apologize deeply.. I didnt know it was you!.”
