How do I talk to a guy that I've never talked to before?

[Kk]

So I really like this guy we are both 20 years old. He sits next to me in one of my classes and I kinda fell in love with his personality based on what I've seen so far and I really want to get to know him more. The was he looks is so cute! It's definitely the look I go for! He's also kinda funny to me! The only thing he's ever said to me was "nice catch!" When he dropped his pen and it fell in my bag lol! That doesn't say much about if he likes me in anyway but it made me laugh! And he just an all around great guy from what I see... I never really talked to him but I want to! His twitter came up under "people also like...." When I followed one of my friends... I was gunna follow him on twitter but I don't want it to be awkward... And I'm really shy so it's not like me to just go up to a guy I like and start talking to him!...What should I do? Forget about him or try something? No sarcastic answers please!!
