I don't really read fanfiction, unless requested by a known source. But I do write quite a few, mainly as a tie-ins or sequels to shelved stories. I do not include any romance, with the exception for this one linked below, because romance is a crucial story element, and was commissioned to be written as such:
Two lovers, a compassionate union, and a forbidden love. Loki, blood brother to the All-Father, and Aletheia, an Atlantean Dikastes; two Isu realms, two hearts, one unbreakable bond. This is their story. Based on Assassin's Creed Valhalla, and commissioned as a five-part story.

And as I commented in my Resident Evil tie-in:
"Respect for the source material AND true love for a franchise is how I write my fanfiction, and I obliged by these simple rules:
Never go against established canon.
Never self insert when creating an original character.
Never include smut or irrelevant romance.
Never disrespect someone else's work.
Never rush writing or force ideas."
