Dear Nobody™,
I don't know your name, nor do you know mine, but I think you're so handsome.
I wish I had stayed just a little bit longer at that table, before I left and went to lecture. I was packing my things, and getting ready to leave when you sat next to where I was standing, at that empty table. You startled me, and when I looked up to see who you were, I panicked because of how handsome you were.
Ever since I saw you, I have been studying in the same area, and I get shy, and look away when I see you pass by. I thought it was odd that you chose a spot that close to me when we don't know each other, and a part of me hopes that it was because you saw me a certain way. Yet I know I'm delusional. I'm a guy who likes guys, while most guys like girls. The subtle signs I perceive are just a projection of my fantasies, but in reality, a guy like you probably has a beautiful girlfriend.
Yet here I am, asking... just in case you want me, please come back and say hello to me? I'd love to know your name.
