[pokedude to shofu voice] You probably have friends and a social life. Hah! How lame! I have my (video games) daughter!
The small slip ups and blunders of his life bring him here, he's embarrassed from recent events and he doesn't dare to speak them up. To get over them, he decides that he'd spend time with one of his two daughters to pass the time between them. Sitting in Nah's room in which she'd sit on the floor and considering Ninurta's height, he decides to sit on her bed and as she sat between his legs, hands run through teal locks of his daughter's hair. He's sure not to use his claws since he doesn't want to cut her scalp or anything at all.
"I'll let you choose, do you wish for me to just braid your hair or should I wash it first?" He questions this because he can help with either one or both if she didn't want to do anything of the sort. Distracting himself with the color of her strands that flow through his hand with ease, he's unsure how they gained naturally and almost the same color or maybe this is just how it was for her. It isn't weird for other to have the same color at all, so he only shakes his head of the thoughts as he looks down in curiosity of what the female would suggest.
Even if he was a prince at one point and maid's did their best to keep him up to par (because his mother wants him to be spoiled, continue on as the prince even though the possibility of him being a fake is high in the beginning.) "I've learned a great amount in doing hair, even at times when I wanted nothing to do with it. I hope you trust my knowledge to the point that I can serve you with it."
