I like a guy in college, help?

Hey!

I just realised that I may have a small crush on this guy that I've been sitting next to in class (just for reference we are in college). We both sit together and talk during class (he talks a lot, however this may just be his personality).. now here's the thing. After each class, he waits for me so that we can both walk together to catch public transport. He also tells me about his friends and talks about his family. Does this mean anything? Is there anything I can do to let him (SUBTLY) know that I am interested? Thanks everyone :)
