Syaoran never would have used the word 'domestic' to describe his guardians. They were often bickering with each other or in battle, sometimes both, so domesticity was lacking in their relationship.
They also showed a remarkable ability to adapt to the world's they traveled to. One world would be a veritable and the next would be an oasis, and his guardians knew just how to react to each one.
That's what Syaoran assumed was happening the longer they stayed in this relatively safe world. It reminded him of his home quite a bit, and it was law mandated that he attend school while they stayed.
It was strange to simply wake up, eat breakfast, take the bus to and from school, and return to Fai cleaning up or cooking dinner. Kurogane got a job and returned home just as dinner was ready every night. Fai would greet him while getting the food on the table, and they would eat as a family.
It was so… domestic.
In this world, the neighbors knew them as father, father, and son. Kurogane and Fai were his parents. Syaoran had looked at them in a similar light since Sakura had been saved, but this world was really making him think it.
Fai was the homemaker, strange as that was to even think. He made everyplace they found into a warm place. Fai did his best to keep up everyone's spirits.
Kurogane was the breadwinner. He hunted when necessary, and even got part time or fulltime jobs when he could. If Fai was losing his spirit, Kurogane was there to piece it back together.
Syaoran was the child. While he could defend himself and likely survive all on his own, his guardians protected him from everything they could. Even when Syaoran was hurt, Fai and Kurogane would tend to him until he was strong.
'We are a family,' Syaoran thought as he watched Fai and Kurogane share stories about their days.
It was one thing to know it, but another to say it. The thought put Syaoran at ease as he finished up the roast Fai had made.
"I'm going to finish my homework," he said with a smile.
Fai watched his retreating form, "Don't stay up too late! It's not due for a couple days!"
"You know he'll be reading until tomorrow, right?" Kurogane huffed just before Syaoran closed his bedroom door.
Yes, they were a good family, and Syaoran loved that.
