While I enjoy this Manga, I really wonder if communication is really that bad in Japanese culture. Is it so difficult to just ask the student why they can't finish their homework? How their situation at home is? Nah, you gotta skip steps and just visit her home to see for yourself, disrespecting their privacy and exchanging one problem for another. In Manga this is usually resolved in a good way, but in real life these types of problems lead to infinite misunderstandings and fights. Sorry for the rant, this Manga is still cute, I just couldn't stop myself.
