Mariiii I have just the right recs for you! Idk whether you have already seen them in Tumblr thooo sorry but it's kinda hard to link them since I am using the app
sukirichi has some great Naoya fics (god girl, true gift, acquainted), suki also great fics for other jjk men and naoya is also in "earned it" but he is more a side character (but if you decide to read earned it, the story is really 🔥🔥🔥 with big twists and it's not yet finished)
satoji's the price of obedience & one too many 🔥🔥🔥 (their fics started my naoya brainrot, seriously price of obedience is like one of the first naoya fics and my favorite)
saintobio's with malice afterthought 🔥🔥🔥
anime-nymph's expectations, if I remember correctly this is about virgin Naoya. 🔥🔥🔥
Thennn for AO3 recs idk if the links will work but let me send them here
A Well Rounded Education by Josucc, this involves the other jjk men too tho 👌 oh, yeah, you should also check out covet and expecting
Fated Arrangement by megumiigf (this is probably my most favorite along with the price of obedience because it is multichapter and ngl, the darkness and angst 👌👌👌)
Sorry if I wasn't able to link the ones from Tumblr and idk if you already read some of them. I hope you enjoy!
(I am still waiting for someone to write Naoya-nii or Uncle Naoya 😭)
YOU HAVE BLESSED ME, GOT ANON. I LOVE YOU SO MUCH RIGHT NOW, YOU HAVE NO IDEA. My thirst for Naoya is pretty extreme right now and I cannot wait to go through and read this list, thanks so much.
