Why is he being strange?Is he shy or stuck-up?

Anonymous
there's a guy in my class who is quite good looking. He normally seems quiet and doesn't take effort to talk to others except his guy buddies. One time, I started talking to him as we walking in the opposite ways. We had good eye contact, smiled a lot and pleasant conversation. I changed my impression towards him and thought that he is not too bad. But the next time I saw him in class, he totally ignored me, like I was invisible. So I didn't care looking or talking to him anymore as I thought he is strange. A week before school holiday, he suddenly came and talk to me again with a smile when I was with my friend! But this time he was a little bit edgy, didn't look at me straight in the eyes. What the heck is he doing?

Last year, I guessed he had a crush on me, or some sort of attraction. But that was last year, I don't think he is crushing on me anymore, but it is still awkward even though I made effort being friendly and treat him like any other classmates. When he sees me, he either choose to ignore me or if he talk to me, he just said hi how are you going? and then standing by me quietly until I say something. If he makes effort talking to me, why can't he be more enthusiastic?

He even got upset with me when I talked to his friend and helped his friend finding a job. I did that just simply because his friend is nice to me

any ideas, what kind of person he is?
