Gosh, there's a lot, but I think my favorites are either exes to lovers, or friends to lovers. There is something so satisfying about a fic where you end up with someone who knows you so well.

Especially if it's exes to lovers? Like, someone has loved you for so long that they know you so well, and then it turns out that despite the break up, whatever that may be, still loves you despite all of it? And will continue to love you regardless? so damn good.
