Crushes Suck

Okay so I just need to get this off my chest and rant a little. There's this boy that I've liked for about 2 or 3 years now. He's the cutest little thing and has a great sense of humour and no matter what I do, my affection for him always lingers. I'm guilty of doing some slight stalking on social media, which only makes things worse. He's a year ahead of me but we had math together in my freshman and sophomore year. We didn't talk during freshman year, but he sat right next to me in sophomore year. Idk why, but I'm really good at math. I practically taught that precalc class and everyone (including him) came to me for help. At a few desperate points, I even helped him cheat (but I would've helped almost anyone in that situation). It kinda fed my affection for him because I was actually talking to him and it felt like there could be a chance of something. I remember he walked with me to class once because I was playing Pokemon Moon in precalc and reminded him of his Pokemon days. I was so giggly and jittery afterwards. Whenever he gave me something as a thank you for helping him in math, I treasured the shit out of it. He called me a genius on multiple occasions and even said that I was really pretty (and he said I would be the "ideal korean girl" which made me laugh because it was an odd compliment but I understood where he was coming from). I helped a lot of his friends study too so I was a little closer in that respect. Thing is, I know that I'll probably never have him. He's just kind of... in a different social group I guess? We have a lot of mutual friends, but the ones that we don't share are super intimidating. I know he had a girlfriend last year, but idk if they're still together. The only people who know are my internet friends, my very best friend, and my best friend's boyfriend (who's in college now). However, someone who I think is a mutual friend texted me the other day because he has a major crush on this girl in his grade and I'm contemplating telling him my secret, but I'm not sure.

I should probably add that the boy I like IS Korean and so is the majority of my school. The "ideal Korean girl" thing was because he was talking about how he doesn't fit Korean beauty standards because he's tan but I rarely leave my house or go in direct sunlight so I'm extremely pale.
