First of all, I didn't plan to watch the drama, because I am not a fan of Jang Nara (and before I watched this I wasn't a fan from Seo In Guk either). After I watched the first Episode I dropped it, but then I read a lot positive things about the drama and about Park Bogum. So I decided to watch it at this weekend. And I don''t regret it! Story: The Story sounds good, but it wasn't the main reason I decided to watch it. Usually, I don't like criminal Dramas. The story have to be very good and interesting so I watch them. But how I said, the story wasn't my main reason for watching this drama. Acting: Hm, with who should I start? I think I begin with the Actor who surprised me a lot. Seo In Guk. I watched him in Reply 1997, but I wasn't a fan of his acting skills. So after Reply 1997 I didn't watch dramas in which he acted. But he suprised me in the role of 'Lee Hyun' who searches for his long lost brother and a killer. I know SIG as a singer and I like his voice, but in this drama, it were the emotions and his acting with his eyes, which made me to a fan of him. Jang Nara was okay. I didn't expect too much because I don't like her very much. I don't know why, but I watched her in School 2013 and there I didn't like her, too. So her Acting was okay. My lovely Park Bogum (I am in love with him since his Acting in this drama) was excellent. I don't know why I love his character (I shouldn't like him, I know...). But his acting is so...real. I didn't have high expectations, because I didn't know him very well before this drama. So it was Love at first sight and I am so excited too see him in Reply 1988. Choi Wonyoung surprised me a lot. I saw him in 'The Heirs' and 'Kill me, heal me', but in a role like this, I didn't see him before. His acting was wonderful and sometimes I was afraid of him. Fazit of the Actors: Seo In Guk was a big Surprise, Jang Nara was okay, Park Bogum was excellent and Choi Wonyoung was wonderful in his role. Music: The Music was good, but not excellent. Sometimes I wanted to cry because of the Music, but all in all it was okay. It suits the theme and most of the time the music suited the scenes. Rewatch Value: I will watch it Again, when I have more time and when *SPOILER* I get over the ending *SPOILER ENDING*
