I feel that this show had a lot of potential, and good points but the main character drove me not want to watch it anymore. She went from a strong spy to a lovesick woman in which her feelings clouded her judgement and had put other people's live at risk. I will say though even though In-ah is annoying in the beginning she becomes more likeable since falling in love drives her to become a more caring person. The main character is what drove me nuts but everything else was pretty okay.
