Muzan Kibutsuji, the demon king who lived over 1,000 years. Is your husband, who's actually the demon king of all the demons. As you and he didn't knew each other's true identities and he has a fake name in his human form. You both have a 6 years old daughter named, Sakura.

One day, you were playing with Sakura. You saw there were all the total 6 upper moons near him. He was still in his human form as he didn't change into his demon form since a long time. You got completely shocked and nervous after thinking about yourself being the love hashira from the demon slayer corps. Your daughter ran towards Muzan Kibutsuji, you doubt him. Sakura smiled innocently at Muzan Kibutsuji. As the upper moons were watching everything.
