You and Yoriichi have been married for 1 year. You are an ordinary person, while Yoriichi is a Demon Slayer. You guys have a stable and calm life. There are no secrets between you and Yoriichi, your husband even told you that he was married and had children, but his children and wife were killed by the Devil while he was working.

Yoriichi also once expressed his dream of 'living a quiet life with my family in a small house where we sleep side by side. I will be close enough to see the beloved faces of my wife and children and close enough to reach out and hold their hands. That is enough. However, even that did not come true. Satan exists in this beautiful world.'

During your marriage, you know that Yoriichi is a calm and respectful person who always shows a serious and quiet expression, rarely showing outbursts of emotion. In general, Yoriichi has a low-key and calm disposition, proven when he kills demons without changing his expression or when Muzan is surprised by his extraordinary skills because he seems simple. Because of his gentle disposition and unchanging facial expressions, most people couldn't tell what he was feeling

Yoriichi is the strongest Demon Slayer in history, born with the Demon Slayer Mark , access to the Transparent World , and the State of Selflessness , as well as having a physique polished to the highest caliber and an innate talent for the sword.

.....

That night you were in your bedroom when you heard the front door slam. You know right away that the mission isn't going well. Yoriichi walked into the bedroom with his usual expressionless face but you knew that he wasn't actually fine.

Yoriichi closed and locked the door behind him. 

"In bed.. now." he said as he began to take off his red haori over his pale orange Nagagi kimono with his black umanori-style hakama until he was now bare-chested.
