I really appreciate you compiling this for me and shit. Unfortunately tho I've read all of this besides the "Who will you kiss" which I didn't like cause of the art. Nevertheless thank you so much for the effort!!!
Yeah i guessed so they're hard to find but you can look through the poly / poly bls tag and hope to find smth :")
I need some BL poly relationships where they all end up together! One where they're green flags too plss. And preferably complete if not lots of chapterss
