Guys, This boy like my pictures but don't follow me. What should I do?

Ok so it's a guy that's going to same college as me in the fall. I introduced myself on IG and we talked to times. I follow him but he don't follow me, but he like my decision day post and I posted yesterday pictures for my pinning ceremony and he like them. I'm so confused on these what these signals are. What should I do?
