This drama was amazing. I liked almost everything about it, but after watching it, I am still confused. Though it seems like the show is wrapped up, some things make absolutely no sense. Like, I loved the story, it was compelling, the acting was great but there were some things just missing. I kind of wish they made it at least one episode longer to address some parts of the plot

Overall, I loved the main characters and their acting. Su Hyeon is a wonderful assassin-wooden log. Nana is so great as Do Hyeon jin, although really, some more exploration into the depths of her character would be wonderful. I would have liked to see more about her childhood after she was adopted. How did she meet the reporter man?
Seul gi is adorable really, and so was Philip. I wanted to see more of Philip.

Plot holes:
1) Ko Hyeon Woo mentioned that Seul gi is Su Hyeon's daughter... How? Never explained again, apart from that one line. I was waiting for them to explain that uptil the ending credits.
2) Why did Hyeon jin's reporter boyfriend die? What is his connection to Seul gi's grandfather, and what happened there? It was never explained why he died near her grandfather, as he lived in Seoul and Seul gi's grandfather did not. Even if we assume that it was ordered by Do Jae Hwan as a pre emptive measure for the article, why would he get Pavel to do it, and why was the notebook burned?
3) What is with the Blue eyes thing? We see sometimes in the starting of the drama, that the kid ML had blue eyes. Why? It was never expanded on.
4) Somehow, Philip was doing something shady, like playing both sides of the field- both with Karimov and the client, but somehow it was never explained why? I guess money, but they really could have put one scene in explaining that whole part.
5) Yoon Ji hye's sister is not a plot hole, but really they told us absolutely nothing about her.


Things I would have like to see more of:
Philip and Su Hyeon's backstory. Flashback of how they met.
Pavel and Su Hyeon
Su Hyeon and Do Hyeon jin's mother
