I'm a little interested in this girl...?

So a few days a week during my break I study at a quiet lobby. Next to the lobby is an esment/Testing center which has gl windows along that wall. I always see this girl work there, and she knows I'm here too. Shes very cute but I don't know if I want to talk to her yet, maybe just make her life more interesting first... so I'm thinking I'll sneak something simple like a rose with a message that says "You're beautiful, hope you have a good day! ~Secret Admirer" or something, put it on her desk before she comes in to work. Wouldn't that be cool? What do you guys think lol
