Spoilers ahead.
It starts with the main character, Tanaka, adopting this abandoned girl named Naa-tan in a surreal scene, in which the girl is inside a cardboard box waiting for someone to take her, just like a cat. She acts meekly and submissively at first, showing an innocent and naive side, which makes for cute scenes. Meanwhile, Tanaka, who seems to be twisted himself, takes advantage of her and quickly takes his position as her "master", even being abusive towards her. At this point, the story seems pretty predictable, but it twists when the girl starts to slowly become more assertive, which culminates in a great netorare scene involving Tanaka, Naa-tan and Tanaka's girlfriend who dumped him. After that, it's shown that the girl has completely dominated Tanaka, even humiliating him and denying him any pleasure, while staying at his home. This manga explored the well-known idea that a cat can manipulate its owner in a funny, appealing and subtle way. The art is really good, especially when showing Naa-tan's licentious expressions, and the ecchi scenes are amazing. This one-shot is a masterpiece for me, it entertained me on many levels while being so short, and I thought its idea was compelling. The only thing I didn't like about it when I was reading was Tanaka's behaviour, but in hindsight, I think it was suitable after knowing how it ends. The story brings many themes that would be a turn-off for many people, so it's understandable why it's rated so low by many people, but it can be great for people who are into those things. It was a good thing for me that it didn't go for the boring, usual romance and instead went for something wicked for a change.
