OMG! So beautiful!! Usually I'm not a big fan of the cutes kdramas. I like more mature relationships, and all the get together tires me. But this drama was SO different even being a little more of the same. Their chemistry is awesome, specially while she's the robot. And their acting was also fantastic - I felt with him, and I believed she was 2 different beings. The story is also very interesting, tuned with the reality and today possibilities. The support cast is also SO great. Usually I don't even think about rewatching a drama, but this one is worthy. Loved it very, very much!
