Another aspect for a fanfic could be how Yor and Loid deal with Anya's school problems together. They might have different approaches at first, but as they work through it, they start to understand each other's parenting styles better. This not only affects their relationship with Anya but also deepens their connection as a couple. Yor might be more instinctual, while Loid is more strategic, and finding a middle ground could be an interesting journey in the fanfic.
Well, a simple fanfic could just be about Yor and Loid sharing a quiet moment at home. Just them talking about their day, and slowly realizing how much they've come to rely on each other. It's a sweet and simple concept that shows the growth of their relationship.
