@Airwave2k2 I didn't interpret Koi's monologue as degradation at all, but instead coming to the realisation that her parents are also regular humans, and they've had life experiences that every person has had, with obvious variations. Instead of just seeing them within their role in the family, they can see them as their own individual. They're both being stiff and overly polite because they're understandably coming to terms that they have a new parent, but in order to get over that stiffness they need to understand that person more, in order to grow more comfortable.
It seems to me you interpreted it as really negative, just because you recognise someone as a person doesn't mean you just get rid of a bond you have with them. It doesn't break down the wall but rather sidesteps around it in order to facilitate their bonds
