Then, gradually increase the intensity of their interactions. Maybe have them share a moment of vulnerability, like Kai revealing a fear to Hilary or vice versa.
In fanfiction, you can develop their relationship by putting them in situations where they have to depend on each other.

Also, show their internal thoughts about each other, like Kai secretly admiring Hilary's tenacity.

A unique way to develop their relationship is to give them an unusual shared hobby. For example, they could start collecting antique swords together. As they search for new pieces for their collection, they learn more about each other's tastes, dreams, and fears. This shared passion would strengthen their bond in a different way than just the typical married couple activities.
