Should I give him my number?

It might sound stupid but I (16F) want to give my number to a guy whom I know nothing about. I only met him because he sat next to me a few times during breaks, and welp, he caught my eye, lol.

I was thinking of giving him a little note with a compliment and my number, since I'm too shy to ask for his and I feel like it's better if in case that he's not interested and decides not to text me. :')

Also, would this be creepy? Because we've never talked before and omgimsoscaredhelp
