<human>: Could you distill the essence of the text into 1-3 sentences?

I recently started summer classes. I am in a small class of just fifteen students, and a lot of us already know a few other people in the class.  I, however, only know about three of the fifteen. Of the twelve I do not know, there is one particular male (I think 21 years old) that has caught my attention. He is very attractive, and I have seen positive posts about him on my facebook news feed. I also recently saw he is a redditor, so this account is a throwaway.

The class itself is a more laid back class, and we have a lot of time to socialize with each other and our professor. I'd like to approach him and talk to him, but I am socially awkward and have no idea how to go about that. In addition, he is 99% of the time surrounded by the same 3/4 girls that are his friends. The other 1% of the time, he is with the professor. I've thought about trying to wait around after class to introduce myself, but he leaves with his friends. I feel like it would be awkward if I tried to introduce myself with all of them present.

Is there anything I can do to approach him in a more casual way, just to break the ice? What should I say? What can I do to make sure I don't start off on the wrong foot?
<bot>: Attractive male classmate is always surrounded by friends, I want to say something. Don't know how or what to say.
