They could have more deep conversations about their future as a family. For example, discussing how they want to raise their children, what kind of values they want to instill. Also, showing them supporting each other in small daily things, like Lucy helping Natsu with his reading skills and Natsu helping Lucy when she has a tough day at the guild. This would strengthen their bond on a more personal level.
One way to develop their relationship further is by introducing challenges to their family life. Maybe one of them gets seriously injured and the other has to take on more responsibilities while also being there for their partner. This would show their commitment to each other. They could also have family traditions that they create together, like a special dinner every week where they share stories. This would give them more shared experiences and deepen their connection as a family.
In a family fanfiction, their relationship could be developed by having them face a family crisis together. For instance, if there was a prophecy that their family was in danger. They would have to work closely, trust each other's instincts, and combine their magic powers in new ways. Along the way, they might discover new things about each other, like hidden fears or hopes for the family. This would make their relationship more complex and stronger as they overcome the crisis as a united family.
