When a guy follows you on Instagram?

Anonymous
So I've known this guy for about a year maybe not even and we aren't close nor do I consider us friends, I'm more of a customer since I go shopping at his store (where he no longer works anymore) we would always talk every time I seen him, he would stare and look directly into my eyes while talking, etc. First I should add I have a really big crush on this guy, like literally he's super sexy and not just his looks, his personality. Anyways I decided to suck up my fear and follow him on Instagram (because I like him, we dont know eachother personally, just talked about every weekend) and he accepted the next morning and with a huge shock he requested too follow me back and liked a pictute I posted about 3 hours after. Is that a sign of interest? The only reason I followed him is because I like this guy so much, other then that I wouldn't of followed him. Could it be the same for him?
