Is he interested ? I'll answer yours?

This guy on insta that goes to the same school as my friend started commenting on my pics randomly for example one day I posted a pic of being at a place and commented saying he was there too ! And when i said sucks that we didnt get to actually meet he responded with yea next time for sure tho.

Again idk him but my friend does and apparently he's really sweet and caring but isn't really chatty with girls so could this be a sign he actually likes me ? And if so what should I do about that cuz he's actually kinda cute ?
