I'm usually good at reading the room but SOMEHOW missed that my friend's friend was into me

So like I'm actually pretty good at picking up on vibes, right? But apparently I'm TERRIBLE at noticing when someone has a crush on me lmaooo. Anyway turns out my male friend's friend is into me. And my male friend's whole wish is just for him to get acknowledged by me once, even though I'm already dating someone else. Like he just wants ONE greeting and it wouldn't be bad to get closer?? Honestly I wasn't comfortable with it so I decided to just... not engage. Would just walk past him in the hallway, not make eye contact, you know.

But THEN one day I went to the nurse's office during class and on my way back to the classroom, I see this guy coming down the stairs with his backpack like he's leaving early. We literally bump into each other and we're both just standing there frozen. I try to move one way, he moves the same way. I go right, he blocks me again lmaooooo. I literally can't move because he's right in front of me and I can only see his chest since he's a bit taller.

And THEN. This absolute psycho goes "Can I... not say hi to you?" with the most pathetic tone I'm not even joking. So I'm like "huh?" and I look up at him and he LITERALLY gets shocked, makes eye contact, and whispers to himself like "wow... you're actually really pretty" SIR??? I'M NOT MAKING THIS UP ㅠㅠ NOT MAKING IT UP.

I literally felt so flustered my face turned BRIGHT RED and I just sprinted down the stairs like three steps at a time. Then I just stood there for like 2 minutes trying to process what happened before going back to class.

Anyway now he's my boyfriend lol.
