To put it simply, the drama was not good. Selling a love story between an android and a human is a tough task on its own but the lack of chemistry and a functional dynamic between the two made it an impossible task to achieve. Not only the female lead was bad as a character but her inconsistencies pilled up more problems. Allegedly, she was his bodyguard and a strong headed ex-UFC fighter but she always ended up being the weakling princess who needed saving. I thought the drama might do an interesting play between the real guy and his duplicate android but the drama didn't put in the slightest...
