I liked the storyline. However, I feel that the title does not match with the story. After reading the title I thought that probably Song Yoon Ah isn't the mother and that Kim So Yeon was the mother. But anyway, keeping this aside, it was overall a very great and enjoyable drama. I decided to watch this drama after seeing Kim So Yeon in The Penthouse. I really liked her acting and I watched this for her.

Although this was a thriller genre, it was quite light-hearted as compared to Penthouse. It's interesting and you can watch it with family. If you are into thrillers but are too tired of the intensity, you can give this drama a try.
