This drama is rather disappointing as this is starred by top actors yet failed to use that advantage. The story is rather repetitive and the only thing that kept me going are the mystery cases and not the main story itself. The premise, that is: a butler is rude/sadistic to her spoiled ojou-sama, could have opened a lot more side stories and conflicts which could have perked up the drama. It is really a good thing that this is mystery drama, otherwise, I really don't know what I'll say.
