What to do if you know a boy likes you?

I, in my infinite wisdom, have no idea what to do next. School has been in for three weeks, I met this guy (We're both Juniours) in my geometry cl about two weeks ago. He's really cute :3 Anyway, he's come up and talked to me a few times, seems nice, not too shy and he's not a jerk. Today he started a note- seemed innocent enough- he asked me if I like Anime. Well, after a few minutes, I asked, "Do you like anyone at this school?" To which he replies, "A few, one in here... It's you." (At this point I was like, "OH MY GOD!!! *Squeel*") Anyway, I replied with a ditto and we talked some, he asked me where I lived, etc. What do I do next????
