One possible plot could be that they face challenges in protecting their unborn child from the dangerous ghoul world.

It's a tender and passionate kiss that symbolizes not only their love for each other but also their hope for a better future in the dark world of Tokyo Ghoul.
A fanfiction might explore the idea of Kaneki and Touka's married life in a more comical way. Maybe they argue about who does the dishes, as ghouls don't really have normal eating habits. Or they have to deal with their friends constantly dropping by unannounced. Their relationship would still be full of love, but these little everyday situations would add a touch of humor to their married life.
One possible fanfiction could focus on Kaneki and Touka building a life together after the chaos in Tokyo.

Kaneki and Touka could be in a situation where they have to team up with some former enemies to save the ghoul community from a new threat. This would test their ability to forgive and their leadership skills within the community.
For Kaneki, it would likely make him more protective. He's already been through so much, and now with a child on the way, he'd be even more determined to keep his family safe. Touka, on the other hand, might become more nurturing. She has always been strong, but the pregnancy could bring out her softer side as she prepares to be a mother.
Perhaps their baby is born with extraordinary powers. In the fanfiction, it could be a symbol of hope for the future.

Touka, on the other hand, is drawn to Kaneki's kindness beneath his tortured self. Fanfic writers explore how they support each other, grow together, and face the challenges of their ghoul - human coexistence world side by side.
In some fanfictions, Kaneki and Touka team up with other ghouls to fight against a common enemy that threatens the existence of all ghouls. Their relationship is a key factor in bringing the different ghouls together and leading the fight.
