Advice?

So I’m in Highschool (freshman) and Semi is coming up on feb 14 aka Valentine’s Day lol. Anyways I have a crush on a senior but he doesn’t really know who I am (we’ve never talked or anything, but I have him on insta and we make lots of eye contact) I was wondering if there was a way that I could talk to him or just any tips on how to approach him. I’d really appreciate it. I know a lot of you guys might be thinking ur a freshman don’t date a senior or something but he’s different he’s on school council and stuff...
