Seeking Japanese ethical drama

Personally, I think "The Last Friend" reflects the social phenomenon in Japan now. In fact, it is a bit ethical, so is life, and it feels a bit biased. Sister and lover are ethical, so are "dear friends", such as nocturnal, female emperor, street children, freezing point 200 1, black sun, hag, and so on. I just want to make a suggestion and push it. Yes, let me say something beside the point. Watch anime, you can go and see SKIP BEAT recommend you! And the condition of the witch!
