well-written fics that are less known (less than 1000 kudos)

So I generally sort by kudos on ao3 and i have gone through all the top ones. Now more often than not I come across fics that are not very well written and it's been really difficult to find good ones

If any of you could suggest good fics that have less than a 1000 kudos, or are outside of ao3, I would really appreciate it!

i also prefer fics that are mature/explicit
