OP here.

Haha, I haven't actually said anything yet. I'm already really embarrassed so I can't bring myself to say it out loud. I already have enough trouble admitting that I have a crush at all.

Well, since it's near the end of the school year, I've been studying really hard for AP tests and other exams, but with this whole deal on my mind I couldn't really concentrate so I told a friend of mine in order to get it off my shoulders. She's quite trustworthy, but I forgot that she has advisory with him, so the conversation went something like this:

Friend: I know someone who likes you~~
Crush: ...Does it start with a <letter>?
Friend: Yeeessss~
Crush: ...Is the second letter a <letter>?
Friend: Yess...
Crush: Does it end with a <letter>?
Friend: ....Yes... Orz

So he pretty much figured it out and she confirmed it for him. I suppose I was being a little obvious, but still I'm quite embarrassed. But at least I didn't have to put him in an uncomfortable position. And a rejection would probably have jeopardized my grades. Since he's been acting completely normal, though, maybe I can put it off until after exams. I know that I'm probably hiding from it all, but whether I get rejected or not, it will still be taking the majority of my thoughts when my future seems to ride on my exam scores.

On the bright side, he talks to me and holds perfectly normal conversations instead of trying to avoid me.
