If you've been poking around fanfiction sites wondering about 'Bestfriends Shouldn't Know What You Like?', I’ve actually gone down that rabbit hole more than once and can share what usually turns up. My searches tend to start on Archive of Our Own and Wattpad, because those two host the widest variety: full-length rewrites, drabbles, and slices of life focusing on shipped pairings. For this particular title, the volume isn’t overwhelming—expect a handful of short pieces, a couple of translated drabbles from non-English creators, and maybe one or two longer AU takes that reframe the characters in a completely different setting. A surprising amount of the fan activity shows up as headcanon posts or microfics on Tumblr and Pixiv rather than as polished longfics, so if you like quick, emotional snippets, those are gold mines.
When I want to dig beyond the usual, I search by character names and ship tags rather than the title alone, because people often shelve their work under the pairing or trope (like 'friends-to-lovers' or 'secret crush') instead of the original title. On Chinese platforms like Lofter or Weibo you’ll sometimes find raw translations or fan comments that reference fanfics—so if you can tolerate machine translations, those places can reveal content that’s otherwise hidden. I also keep an eye on fanart; a piece that hints at a ship will often lead me to a fic in the comments or linked in the artist’s profile. Pro tip: search using quotation marks around the title on general search engines, and combine that with site-specific queries (e.g., site:archiveofourown.org "'Bestfriends Shouldn't Know What You Like?'") to catch cross-posts.
From what I’ve seen the community is small but fiercely creative: lots of angst, a fair amount of soft domestic fluff, and the occasional crack fic where the premise is stretched to absurdity. Content warnings are worth checking—some writers tackle heavy themes and will label their works accordingly. Personally, I love finding a tiny, unexpected fic that captures a single perfect moment between characters; it feels like discovering a secret track on an album. If you’re patient and like poking through tags and comments, you’ll find neat little gems that make the whole search worth it.
