Answer

Breeze - to move in a self-confident or jaunty manner, or to say something in a jaunty way.

The sheet - it would be covering the rest of the body too.

Enjoyment - the writer/speaker thinks the girl enjoyed rejecting his advances.  That may be a good sign (if she derived enjoyment out of interaction with him, even if it is an act of rejection), hence "upside".
