Douma Reborn: The Love Between Douma and Kotoha

Looking for Demon Slayer Fics!

I'd like a completed novel, or a long ongoing one. The protagonist can be male, female, human, or ghost; anything is fine, but no two male leads! The protagonist must have a clear stance, whether human or ghost. They can hesitate for a little while, but don't spend entire chapters wavering. No trying to please both sides; it's so frustrating.
