Troubles

I honestly don't know what to do here. Him and I were best friends in middle school and I remember that he always really liked me and he would give me love letters when we passed in the hallway me. I remember having no interest in him and I just liked being friends. When high school started we parted ways, like big time. I became a cheerleader and I've never really ran short on guys to talk to and go on dates with. It's Sophomore year now and I can't stop thinking about him. He never leaves my mind. I don't know what to do especially since I have no way to talk to him. He has ZERO social media accounts and I only have one class with him, choir. And in choir we don't ever have opportunities to talk to people, we work from the beginning to end, no breaks. On a blue moon I'll see him before school waklking around but we're actually both pretty shy people, so I'd feel strange just walking up to him. I have his best friends snapchat and we text sometimes... but the problem is his friend likes me, and I'm not going to ask him for his friends number, I hate hurting feelings. I honestly don't care about much of the other guys that talk to me, they're nice, but I feel like everyday I like him more. I've been trying to give him 'the glance' but that's not really work because he doesn't really pay attention to anybody who isn't the choir instructor which makes sense. I'm also scared that if I put myself out there he wouldn't like me, or even reject me because of his friend. I don't know, I just need advice.
