I like my {kung Fu} teacher! what should i do?

okay so technically hes not my teacher but he helps my teacher sometimes to teach the cl when my teacher is busy. so I like him a lot because hes Really nice, smart, funny, cute, and is amazing in his job and he does card tricks which is awesome but the problem is hes 19 and im 16. I asked my parents is i could date him "He doesn't know i like him" and they told me they would let me, but My teacher would say no and etc...I really like him and hes awesome but the bad thing is hes going back to new Hampton. {where he lives] because he only visited us aka [my teacher] [one of the 7 dragons] just to meet my teacher. I dont know if he likes me or not but i dont know what to do because im very distracted at times. and one time he, my bestie, and her brother where in cl and he was talking about stuff and i was like "yeah sure okay" and i fliped my hair and i looked back at him and its like he was hypnotized or something but in the good way like he was standing there and staring at me and smiling.and it was awkward because everyone was just standing there while he was looking at me and it was an awkward silence . any-who hes moving away next year and idk what to do. help.
