You will probably be confused a lot lol cause some actions you may think they like you but you have to be careful that there intentions are good cause a lot of guys are just into using girls. He will probably flirt a lot and if you are interested ask him to hang out ( but keep on a friendly level). Just get to know him and see if there is a connection. You don't have to wait to see if he asks you to go out. Just say " hang you wanna hang out sometime"
Before my bf and I were together, he would always try and make me smile without acting like an idiot. He would be really sweet, open doors for me and help out with the simplest (and most complex) tasks. He would also stand up for me, And that meant alot to me. Hope I helped! <3
