Exactly!!! And it's not like they are really Dad and Son...It's just so that they are a legal family and can have legal claim over one another if either is in hospital or in any trouble...Anyone will be able to tell that they are not Father and Son cause their age difference is just 6 years. Both of them didn't have a figure to call "Dad" in their life so they can treat the word "Dad" lightly and have fun with it cause they know that they are not related like that....

losers over here arguing about the morality of a fictional character talking about a daddy kink omg go outside and touch grass
