William Crowne is a ruthless businessman who never takes no for an answer and will do anything to get his way in a deal. Mr. Crowne, as he is called by everyone but his rebellious butler, Levi, acquires a new pet. The pet is a rare neko. The only reason he even bothered with the neko is because it was left to him in a will. As far as William is concerned it can die and it would save him money. However there's something about his new pet that leaves him wondering.
Levi is William "Willy" Crowne's butler, and had been since he was thirteen. He seems to be the only one Mr. Crowne has a soft spot for, however small it may be. When Willy gets the neko pet Levi finds him absolutely adorable. Unfortunately the neko doesn't talk...at all. Levi wants to know what happened to the neko and wants to help him and especially wants Willy to treat the neko better.
The neko has had a bad past, so bad that his subconscious has blocked out all of his memories and emotions. Then he comes to be owned by a man called Mr.Crowne who has a butler called Levi, and the longer he is there, the more emotions start to leak through. And when the memories start to come back everything starts to go downhill.
