It's nothing new of course but this Light Novel logic of class castes always weirds me out, if you want to have the normal looking shy dude that's randomly a loner get side-eyed just by interacting with the pretty shouldn't you at least make an effort in that making sense? At least write them a bit more antisocial or something.
You could argue that maybe it's more believable over in Japan but then you can't help noticing those manga written by girls that use shy MCs like MDuD, Tonaneko, Seihantai and there the classmates mostly act like normal people around them, as they should.
