I have a huge crush on you.

Everyday I look forward to the class we have together, and I always wait for you to show up. I think I'm fairly obvious, but I try not to be. Whenever we have a conversation, all I can think about is hugging you. It makes me sad that we can never date, because I'm too scared to speak up. I hope you have a great life, and always feel wanted.
Can I just hug you?
Just once?
