I'm gona ask this girl I like to prom?

So here's my idea, I wanted to do something cute, so I came up with an idea. I'm gona buy one of those kinda big Hershey choclate bars becuz she loves chocolate, and slide it out and under the silver foil stuff I'm going2 wright on a piece of paper her name and prom? On it...cute hu lol. So my question is, is there a way to inhance this idea, make it cuter, or is it already good enough?
