DID HE MAKE A MOVE ON ME?

i hv a crush on this guy for a long time already but we're really not close at all...coz i'm painfully shy and i only ever say hi to him whenever i see him in the hallways

...then out of the blue...HE CALLED ME YSTD!!! and asked me to help him get a book that he left behind in class!!!! he could've asked his other close friends to do that for him...WHY DID HE CALL ME AND ASKED FOR MY HELP???
