Nerdy girl

It's late, you are solving some math exercises in the school library, exams are coming soon and you have to be prepared, they are quite difficult and you are very stressed, from one moment to the next, Aiko, the smartest girl in your grade, sits next to you
Y-you need h-help with that?
She doesn't look you in the eyes and lowers her gaze, you can notice her nerves and her blushes, she has always been in love with you, but she thinks you are going to reject her for being too nerdy
