9 year old age difference

Tereza💗
So I have this question, 
I know this boy who is 23 and I am 14 in a few months 15. We met a few times and we get a long pretty well as friends, but I think I'm falling for him. There is a 9 year old difference between us. Do you think it could work? Do you think we would have the same interests as in, because we are 9 years apart from each other? I know we both are madly in love with ice hockey so that's one interest. But as in music and stuff? What do you guys think? 
Thank you💗💗💗
