I still remember that one fanfic of Douma x female reader, I think it goes by the title "My Demon Friend" and was published way back when its still lockdown(I think). Whoever published that, why did you delete it;-; it was a damn good story, the ending genuinely made me cry for real like oh my goodness the angst is so good!! If it didnt get delete. Pleaseee! Tell me and I'll reread it again!!!
The story is where the reader lives in a toxic household of their aunt and uncle? I'm not sure I can't remember the start of the story;-;
Then the reader decided to live far away and run a tea shop(I think). That's where Douma stumbles upon the tea shop, the reader doesn't know demons exist, so yeah days later they become friends.
Until Tamayo or Tanjiro(I don't know which one;-;) visited the shop, having a conversation with the reader and that's where they told the reader Douma is a demon. When they left, the reader decided to pack her things but Douma eventually arrived in time. The following, I forgot.
By the way, Reader has some kind of illness or disease and Douma wanted her to become a demon but the reader refused so she end up her dead dead;-;
In the infinity castle arc I still remember Douma be telling "...I lost a friend"(Friend my ass) and Kanao started bickering she lost someone too thanks to him.
When Douma got defeated, that's where he reunited with reader in the afterlife. This is the part that made me cry fr;-;
I don't know what possessed me to read that when I'm not even a Douma girlie.
