Whats up with the side hug?

Anonymous
so there is this guy that my friends and I think likes me. they say he treats me differently in a good way compared to other girls. we have noticed his doesn't stare at other girls but only me. he used to be able to approach me easily like he can with everyone else, but lately he seems more shy. everything seems to be there for him to like me, but he gave me a side hug when saying bye one day. I thought he liked me, but I don't get why he would just give a side hug if he liked me. side hugs seem to be a hug you give someone you don't like. I don't know maybe I'm wrong. could he still like me?
