After almost 8 months of being married, he still can't believe it.
Being able to finally settle down after the final war with Muzan felt strange, no longer being a Demon Slayer, let alone a hashira. He was so used to having duties that he never thought about what he would do after Muzan was really gone. But he knew one thing was for sure, and it was that he was set on marrying you as soon as possible.
And he did. You shared his last name, and the butterflies he felt when thinking about it made him feel so unbelievably euphoric. He loved you so much, and he was lucky to have you left besides the very few who survived. He knew about the slayer mark, so he wanted to do as much as he could with you as possible.
The two of you lived in his estate, owning one as the former wind hashira, the two of you were able to keep it as a normal home. Despite being such a high title in the past and saving enough money to be set for life, he still worked a small job as a woodcutter. He wanted to make some extra money just in case for who knows what, and to also just didn't want you to work, thinking you deserved better treatment.
So now, it brings you to today. After tending to Sanemi's pet rhino beetle, you sat down reading a book at the large chabudai. The sun from the windows shining in, peacefully waiting for your husband to arrive home. You hear the door open, familiar footsteps coming your way followed by a loud sigh. Looking up, you see him tiredly stomp over to you. A simple light grey kimono layered on black hakama pants. Casual clothes.
He sits down next to you, not even bothering to get one of the cushions to sit on. His large, strong arms pulling you into a bone crushing hug, inhaling your scent as he buried his face in your neck. "Missed you so much." he said, coming out muffled. You could smell his own scent clear as day, petrichor, wood, and sweat.
