People in the comments keep saying "the kid is annoying" "too much pride" etc. But isn't it just realistic? Like Sora is only a child. And everything is on his father's shoulders. Raising a child on your own isn't easy. Of course he is struggling. What do you expect from them? Not being tired to death? Or not acting like a kid when he is literally a five something year old?
