It is a very lovely movie, but becomes annoying later, because why in God name will you leave a human like you for a robot, I'm not saying it not bad liking the robot(zero nine), but loving him that is unbelievable, it a machine that can't even reproduce and will eventually melt down one day, too me Wang joon really love Dada, but she letting go of the love for a robot is really annoying and even she crying on every episode for the robot makes it more annoying, because this can never happen in real world.
