Crushing on a straight boy

Hi, so I'm a freshman in high school and I started going to this club after school called model UN. It's a fun club, we get to debate, make jokes and have a good time. There's a sophomore in the club, that I can't stop thinking about. I'll never forget the first day I saw him, he was wearing this red sweater, sweat pants, had his hair messy, and I liked him from the start. I never could figure out why though, he's not overly attractive, he's not in great shape, there are guys way cuter than him, but for some reason every time I see him I just feel more attracted to him. Anyway, the club is every week on Tuesday, normally I don't pay too much attention to the way I look when I'm going to school, usually just sweat pants and a hoodie. Now I wake up early every Tuesday, shower, shave, plan my outfit in advance, and make sure I look great. Another change I've noticed is my attitude towards school. I've always been a bright kid, but after talking to him I found out he was really smart. He's a year ahead in science, two in math, and taking 2 Ap classes. I was only a year advances in math, and grade level in everything else. Suddenly I found myself studying for the Algebra 2 test out, and working really hard to get straight A's, all because I'd didn't want him to think I was stupid. I can't even begin to describe how I feel around him, I'm nervous and anxious at the same time. If I'm ever talking to him, I always have to remind myself to not stare at his face too long. He doesn't know I like him though. To him I'm just his friend, I hope sometimes that he's secretly gay, I have these hopes that one day he's going to tell me that he's liked me all along, and that we're going to live happily ever after togather. I guess that's all they'll ever be, hopes. I've had these types of crushes before, but before I got over it in a month or two. It's half way through the year, and I still get exited on Tuesday just because u get to see him. I'm lost on why I should do, so far I try to talk to him, we actually have a lot of the same interests. We both are huge start wars fans, we both like politics, and we both play lacrosse. I don't think I'm ever going to tell him how I feel, but I don't think I'm ever going to stop liking him either.TL;DR: I like a straight boy, he's doesn't know. I really like him and don't know what to do with these feelings
