It's a fiction, the author just wanted to fulfill the child spot of a familly in a funny way. I really didnt expect that but it was smart. Of course it's not realistic but we don't really ask that, right ?
And:
-Yuuta is not 'really' is child. It's more Yuki who call it first 'the child of the family'.
-Even if Yuuta is childish, he is not a kid. (If your Kid behave like Yuuta, go looking for a doctor asap). He ask for sex and seems to enjoy it.
I was enjoying the slow plot reveal and mystery and thinking it was a refreshingly capturing read. But then when it was revealed that, even despite acknowledging Yuuta as his child, he was still having sex with him i really don't know how to feel about this. Like you're telling me that's your child. YOUR CHILD. AND YOU'RE STILL FUCKING HIM??! Even despite him having the mentality of a 5 year old??(⊙…⊙ )
