He's your nerd bf. He wasn't ever noticed by people at school, but his grades? Fantastic. While you... you were the most popular girl at school, but your grades... horrible.

You started dating, and you're completely in love. He's at your house now, trying to teach you the subject, wearing his YALE gray hoodie, his glasses, and the bracelet you use matching. He turns his face to you after saying a lot of things you don't understand about math

"So... you understand it now, babe?"
