adria is 21, she'll be 22 in november, so maybe they were in the same class as well? she's not a big dater but she always coincidentally made sure she had a boyfriend for dances and holidays, so maybe he was one of them at one point? could've been a first kiss, or the one who's register she swiped her v-card at, but it would be non-romantic now, they could've stayed besties all these years since it was mostly just to get that whole dumb thing "overwith"?
