6/10 max, The concept is pretty good and could have been a 9/10 but the writing of Jo Jung-joo disappoints me like crazy. Seriously, they r so many stupid scenes makes my brain hurt. For example - AI having emotions ???? Seeing pics missing mom????
Further more, the bodyguard appointed by the director is doubted but the vigilant secretary puts her in the same house and not even put her under surveillance and then The hospital scene episode 3/4, Where she follows the secretary gets caught but the apparently smart secretary doesn't pull the video of the hospital to check what she did there. Better writing would have covered these holes.. nothing pisses me off more then a good plot screwed over by stupid writing...
