How should I talk to my crush when he blocked me on snap?

There’s this guy I have a huge crush on in the grade above me. He’s honestly the cutest guy I’ve ever seen, so I asked my friend who is in his grade for his snap. I added him (he wasn’t active like at all) but then he finally got on after a week or two and added my friend back (that gave me his snap) but blocked me. I think he blocked me because when I look up his name it’s not there anymore. I don’t know what to do, since he may have blocked me because he doesn’t know me. We go to the same school but he’s new and has only seen my face in the hallways. I want to talk to him but I don’t have the confidence to go up to him and he doesn’t have any other socials, so I don't know what to do.
