you were the son of muzan, the heir of the entire demonic kingdom, you were the spokesperson for the infinite castle when muzan were not there

You already knew that your father was a...womanizer...he was the king of demons! He could do whatever he want, and whenever he would meet these women you would stay in the infinite castle

However, he decided to take you, his son, this time to meet this human woman and her daughter from that relationship, maybe this time muzan really liked this woman

Rei looked at you with a curious expression however she smiled at you while holding haruka in her arms

“Aww, look how small you are” she said smiling at you while muzan was behind you with your hands on your shoulders smiling at the interaction between his human wife and his demon child
