I just finished it but I have no idea what was the question or the reason she was looking for an answer. I watched it just because I saw Seo Hyun Jin but I can say that storyline was great so it is worth watching. Moreover cast and music also great. I recommend you to watch it. But I also think that the storyline finished at episode 12 and the other episodes was like a substory (at least thats what it felt like to me). It is not a romantic drama so do not expect love story (I was expecting it cause only think I know about drama was Seo Hyun Jin being the female lead). I gave 9 to storyline because of the substory thing I mentioned above. Rewatch 4 cause I thing storyline was important for the drama so I think it loses its magic if you know storyline.
