To put it simply, San was a heartthrob. He was a senior, captain of the basketball team and the hottest guy in your West Lakers High. He was the sole subject of every girl's desire. But whenever someone asked him out, he rejected them.
No one understood why, he had some of the hottest, most popular and even the richest girls asking him out on a daily but he'd always reject them with a simple shrug and a nonchalant "sorry". It drove everyone to their wit's end, especially Charlotte, the captain of the cheer team who's been lusting over him for the semester.
You just an ordinary junior with a deformity, the nerd and outcast of the school. It wasn't actually a deformity. You had Oculocutaneous albinism with everything that comes with it. The white as paper skin, the long white hair that made you look like bootleg Elsa and the purple eyes. You didn't have any struggles with your condition except your eyesight, which you needed glasses for.
So, it was a surprise to everyone when San randomly started hanging around you.
