TIFU by prank calling my friend’s crush

I F(16) pranked called my friend’s crush during one of our hangouts. We were bored and decided to call this guy who liked her and who she was interested in. He went to a different school so I decided to use my actual number to call him so he’d be more likely to answer. He ended up picking up the phone, and I won’t lie, I was basically messing with him the whole time. My friend would tell me inside jokes she’d overhear from his conversations with his friends in the class she shared with him and then I’d reference them to him on the call. After the call, he texted asking who I was, and me being a creep, I said I got his number from his best friend. Like a month or two later, me and my friends hung out again and decided to call him. When he didn’t answer after like the 5th time, we called his best friend who I had a pretty good (and funny) conversation with for half an hour. If that wasn’t weird enough, we basically created a whole fake identity and made a Snap and Instagram account to solidify it. We literally spammed them as they were practically our hangout entertainment anytime one of us came over. Reminder: this is all happening with my very real and very personal phone number. I assumed I would never ever see this guy ever in my life as we didn’t go to the same school and had no mutuals besides my friend. He was just an ongoing joke in our little trio. Well guess what. I was wrong. We are both going to a new school which has a class so small that they made a WhatsApp group chat for the incoming students. If you didn’t know, WhatsApp automatically connects your contacts to a person’s number so I immediately clocked the fact that he was going to the same school as me. Not only that, if he did save my contact (which I don’t think he did), it would tell him. Reminder! We were so annoying that I asked him whether he believed in hobama (the ship) and would send a picture of Ms Simian from the Amazing World of Gumball with invisible ink whenever he asked what I looked like. Long story short, I think him and his friend blocked me. This school is so small that if we ever become friends or get put in a group project together, we will exchange numbers and he will 100% know. I promise I’m usually a normal person, but since I thought I would never meet this guy I didn’t care whether I was weird or not. Any thoughts on what I should do?

TL;DR: I prank called my friend’s crush for months on end, being lowkey creepy, and now we’re going to the same small school.
