There is thi s guy... and idk what he is trying to send me if he is sending anything at all?

In grade nine we talked a bit cause we sat nxt to each other. Near the end of that grade he ran up yo me outside when we were alone hugged me and whispered in my ear i was his favourite... does this mean anything? could it be a joke?? we always look at eachother, and when he get stoned he is always staring at me like right in my eye balls!! he smiles at me alot but we rarley talk cause of different friend groups and is extremley shy.... when he is around people he isnt friends with cause he dosent know ujm that well
