Does it mean anything if a guy does this ?

-Hi guys I would like to know If this means Anything . Basically me and this guy in my class were talking and all a sudden he told me that I have been very nice to him and then asked if I wanted anything because I would always give him a pencil if he needed one , or I would share a snack with him , I then said no that he shouldn't worry so he then got up and walked back and forth next to my table and then went behind my back and asked me " is this how you give a massage "? And he then started massaging my shoulders and then when is friend asked him if he liked me , he looked at me smiling for. Couple of minutes and continued doing is work . And then in biology class after I have a brief presentation he looked at me smiling and then clapped and kept repeating that was good that was good constantly .So I was wondering does it mean anything ??:) THank u !! We are both 15it means he likes you or he's trying to creep you or hes a creepy guy that likes you
