HELP ME APPROACH A GUY?

I’m now crushing on a guy who’s my classmate in school (who I stalked on social media after along time thou we aren’t following each other). We’re both currently doing masters degree in different colleges. We don’t have any mutuals on social media as well. I’m sure he has no idea about me, since we never got a chance to talk to each other during school. So pls give me ideas on how to connect with that guy WITHOUT ADDING HIM ON SOCIAL MEDIA FIRST.
TIA
