Does he like me or what?

Ok so i like this guy and today in biology i help his notes for him so he wouldnt lose them and before he came in i set them on his desk with a pencil cause we were doing a lab well his friend came in and took the notes and i was like give them back! then he came in and i was like ___ he stole your notes! he got them back from him and his friend was like making fun of me for telling the guy i like that he took his notes and the guy I like said "shut the *** up" and i thought it was sweet that he was defending me and not letting his friend make fun of me like most guys would so does he like me?
