Sweet soft comedy about a young office lady (who is working ridiculously long hours), and her cat-carer whom she adopted as kitten, and who grew into large super-intelligent cat who cooks, cleans, takes rubbish out, does shopping, and takes care of his owner. Plenty of good situational humour but nothing extraordinary, very little storytelling, and almost no explanation for most mysterious aspects of the story.
In demanding Japanese (over-)work culture, it takes labour of two people to succeed as one company employee. Main characters' duo shows what it means to support full-time worker who have no time or capacity left for anything at all after work, being completely wasted at the end of each weekday. Strangely enough the show is entertaining, as idea of a cat with human intelligence have potential for many humorous situations.
