This is not a drama that is heavy on plot - it requires a lot more suspension of disbelief than typical in a show that no matter how socially awkward a person as intelligent as Min Kyu would believe Ji Ah is actually a robot. The important thing to know, though, is that it doesn't make a bit of difference to how enjoyable a show it is. I found it to be sometimes sweet and sometimes silly, but there were also poignant moments that showed depth to the core group of characters (who were all portrayed brilliantly). The plot may be ridiculous, but it is genuinely funny most of the time. This is definitely more of a comedy than a romance, though this does not negate the sweetness of the love stories.

The parts of the plot that were meant to be suspenseful and dramatic were less successful than the comedic elements. This is perhaps due to the lack of focus on them at all; in general they seemed more disconnected from the rest of the plot and characters due to how little interaction there was between them to cause tension.

This is definitely a drama worth watching if you're in the mood for something to put a smile on your face.
