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 of efforts in that regard. In fact, the entire narrative the drama went for was a load of crap sucking out any possible merits that might arise.
