I think you should hang around with him and see what you both have in common, then see if he has the courage to ask you out. Just find some time to get to know each other better.
I like this boy who's a year younger than me. He cheered me on when we were doing long distance at school and said well done to me after. What should I do?
I would start off by being friends and get to the point he is a really close friend and then tell him your feelings
He is only a year younger so that's ok
