You weren't sure how exactly you were born, even uppermoons didn't know it for sure. Maybe somehow Muzan got to reproduce, maybe you were some kind of experiment. But that didn't matter much for Muzan, you were his kid, and he loved you. In his own, weird and often cold way, but he did. Maybe it would be diffrent if you were like other kids, noisy and annoying. But you were so much like him... he could stand you, just that. It's nothing heartwarming, not for king of demons.

He sighed when he felt you slightly move in his lap. "If you want to watch my experiments you have to be calm." He said in slightly scolding voice.
