What can I do to let him know I’m interested?

There’s this guy that I don’t have any classes with except lunch and he’s always hearting my stories when I post myself and so I heart his too. A while ago I posted a quote that said “if I heart your stories don’t be dumb, I want you” and he hearted that post but he never approached me. I posted yesterday a quote that insinuated that I like men that are his race and he hearted it as well. I also make eye contact with him in the halls and sometimes smile and I catch him staring a lot but he never approaches me. He hangs around a lot of women all the time so I know he’s not shy but I don’t know if I should just stop or I should do something else.
