Who cooks:Itachi grew up being cooked for and eating out when there was no time to go home, so he has very limited, if any, cooking experience, Sasuke cooks, since Sasuke was alone and had to learn to cook for himself.Who does the laundry and other chores:With the pair in the household, they learn to both share chores, though Itachi will try to take more away from Sasuke when he can. Sasuke is very underweight and Itachi would be the one with the stamina here, so he will ease his burden.How many children do they have:They have no desire for children, so none.Who’s more dominant:In matters of orders, Sasuke is the more dominant one. But neither of them is actually having sex, as Sasuke is asexual. He'll occasionally tell Itachi to do something and not care for telling him please, because Sasuke's mind demands it. That's the dominance part.Favorite nonsexual activity:Itachi will often read to Sasuke. When Sasuke is comfortable enough and associates Itachi with a feeling of security, he will simply let Sasuke bow into him and hold him. All activities are nonsexual.Their favorite place to be together:In the cabin, with each other.Any traditions:Their daily routine would be their new tradition.Their “song”:I am absolutely shit terrible with putting lyrics and songs to ships I mostly listen to OSTs and associate the emotion the music gives me...? The only thing I've ever chosen was 'Dark and Stormy' by Hot chip.What they do for each other on holidays:Neither of them celebrate them.Where did they go for their honeymoon:There will be no marriage so no honeymoon.Where did they first meet:Itachi first met Sasuke a few hours after he was born and swaddled, and his mother let him see his baby brother for the first time.Any pets:None.What do they fight over:Nothing. Itachi is not argumentative by nature and he will not argue with Sasuke.Do they go on vacations, if so whereThey will only venture outside the cabin to the market, and that is not a vacation. So none.
