Jung Chae Yeon is gorgeous and makes a believable stoic robot who learns to emote. The plot is ok but could have had a better dramaturgical build-up. The ending was quite unsatisfactory, too. Some of the supporting actors came across as just as robotic as Annie, which probably wasn't intended. I especially could not warm up to her unnie (forgot her name). All in all it was cute but it didn't really touch me. I had to motivate myself to finish it, even though it is super short, I almost did not finish it.
