the line idea is they had unrequited/unknown crushes on each other in high school, ran in different crowds but had close last names so they shared homeroom together, maybe even had a required class or two together. they went separate ways after high school and have both lived very different and full lives. now they’re both around 30 and life has brought them back together unexpectedly and those crush feelings resurface. i was thinking the sudden death of a classmate would be the catalyst.
the expand upon that i would love if maybe he "dated" a friend of hers in high school in the same way he "dated" a lot of girls at once so there was a juxtaposition of her feelings for him and wanting to be a good friend. i really don't see them having hung out a lot ever because they were in different crowds. i was thinking too maybe if he signed her yearbook or gave her a note at graduation that sort of expressed his crush on her and shit but she never acted on it would be an interesting addition too.
