Dear Crush:
I was not expecting to fall for you so hard. Indeed, I wasn't expecting a new interest at all. But you were so... unassuming and smooth, yet striking. Simple, yet fascinating. I am, I admit, enthralled.
You've intrigued me from the start. I know it's a terrible cliché, but not a day goes by that I haven't thought about you. When I first met you, I honestly thought you were out of my league. But you were easy to approach, and I felt so comfortable interacting with you. You're sophisticated in ways that I'm not, and I never even entertained the notion that I'd ever travel in your circles, but you are tempting me to broaden my boundaries.
I'm not good with words. I just wanted to say that I adore you from afar, and maybe one day, I'll work up the nerve to take you out proper. I'll find some way of proving that I deserve you. I do hope you'll be patient with me.
Adoringly,
Xtina
