The comments.... Dayum..
Anyways, I read back after reading a comment and the when nao said smth like we say harsh things to protect ourselves, that's exactly what I thought too? The uncle wasn't really trying to instill anything in the niece. What I precieved was that him thinking the kid would be sad if he heard "it's weird to have two dads." I don't think the uncle meant anything deeper, it was the niece who heard and decided yeah its weird, I'll say it to the kid. Because kids are devil's spawn and they legit don't care.... I'm assuming the one uncle likes has a child? Or he's kinda like nao cus he can't openly claim he's gay like ai, which leaves him kinda cold and bitter. Maybe I'm over analysing, but I don't really think uncle is to entirely blame here. Author did a good job of capturing regular life. And well, go easy on the poor soul, I'm sure these people will solve their own issues like the way they are.
