depends on the variation of the fic. if the story is written in prose—like the ones you’d find on ao3 and wattpad—then it could. prose is where i usually discover new words

buttt, if you’ll soley read socmed AUs, then i think it wouldn’t help much. SMAUs often use everyday words to convey that natural and relatable feel

tldr: yes, but more so if the fic is prose 🤍🤍
