Yo Seung Ho acting here is absolutely incredible: he is capable to transform a superficial story to a real human tragedy. And somehow, although, the story seems an absurd, you can feel every main character's emotional impulse. It's really something when a guy who has to play a rich man with an unique allergy to the people and an affection to a robot girl, makes you feel it as a real thing. Only because of his acting it was worth to watch it and even to rewatch it. So, the story is more than ridiculous but the Yo Seung Ho's acting lifts it to a much higher level, even to an existential drama. But what can I say about the drama itself? Well, it's aesthetically beautiful and emotionally pleasant but other details are really superficial. However, the acting... ;D
