I like drama and all, but this is like real life type stuff. A story about a couple in deep denial about the nature of their relationship and communication problems may be a bit too much for me. I've known people like this and its so painful to watch when everyone but the couple involved can see it so clearly.
Remember, this is Japan where non-confrontation and misunderstandings are the norm, not that it's uniquely Japanese. Of course, the Japanese language, with its lack of subject, dependence on context, etc. is rife with misunderstandings as well. 👫👫👫
