<human>: Can you provide a brief overview of the text?

Hello reddit! So for the past 18 years of my quiet life, I have been mostly forever alone. I have a few close friends, but I've never been in a romantic relationship. Never kissed or been kissed, that sort of thing.

I moved across the country a year ago, changed schools and all that good stuff. Now I've met this guy.. tall (taller than me, which makes me happy!), handsome, and incredibly sweet. I don't know if I can rightfully say that I'm in love with him, but.. I have a really deep affection for him, I don't really know how to describe it. It's more than just butterflies and a little crush. 

Our interactions consist of smiling and waving shyly at each other and short, sort of awkward conversations. But every day he comes up and gives me a strong, frontal hug. I always hug him back, and I dunno.. It's probably just a hug, but it makes me so happy. I've had other guy friends that hug me, but for some reason this feels different. I always feel happier when he's around. 

I know we have just about the same taste in music, but I've found it hard to talk about other things. I can be painfully shy sometimes, but I think I'm ready to try and become closer friends with him at least.

So here's the question. How do I show him that I'm interested, without being aggressive? Should I ask him for his number..? I would at least like to become friends with him, if not more.

You can probably tell, but I am totally clueless. Ever since I moved I've had trouble making friends, and this feels like it's a whole other level.
<bot>: I really like this guy and don't want to fuck it up. How do I show him I'm interested without being aggressive or obnoxious?
