2. Enemies to Friends to Lovers
3. Groundhog Day/Karmic Time Loop
4. SnowedIn Cabin/Isolated Together For Extended Period of Time
5. Adopting/Raising a Baby
6. Hot Single Parent(s)
7. Found Families
8. Friends to Lovers
9. Everyone is Evil/Mirrorverse AU
10. Reincarnation/25 Lives AU
Most of these are no surprise at all. I've written a lot of these, and they easily describe some of my favorite fics across fandoms. If I'm surprised by anything, it's that numbers 3 and 5 are as high as they are, and that number 6 isn't in the top three.
