cute!! the last one i remember reading was oomf's itzy 2shin fic where they were close mutuals for years then met each other irl and became friends (without knowing they were already mutuals...) and the protag was having conflicted feelings bc she thought she was in love w both of them,, you know i can never get enough of alter ego tropes so i love premises like these

i think it'd be also cute to do something where they're rival fic writers who grow grudgingly fond of each other...or maybe only one of them thinks of it as a rivalry. kind of like those 2 fic writers that went viral a while ago
