Hmm, neglected housewife and neglected child. I wonder want if some kind of bond will form between Shouta and that housewife. He's able to relate to Naoto because they are both neglected and was quite happy to hear that his parents are also not coming for 'Class Observation Day'. But with Naruko-san in the picture that relatibity might disappear.
Also their teacher has piqued my interest. Something's off about her, I just don't know what it is. At the very least the continues calls and the fake signature amused her.
