I think this drama is worth watching. I was having a second thought before i give it a try since i read some good and bad review about this drama. However, i'm glad i watched it, i really enjoy the drama. The acting is good, the music is great, personally i love the ending theme song. The story might build up slowly buy every detail worth mentioned, i think the scriptwriter of this drama did a great job on it, i got hooked in from 2nd episode, i feel like this drama has potential and it didn't make me regret at all. This drama is so realistic, i think this fact really make me get hook in with the story easily since you can see those things happen in your daily life as well if you have a careful look around you. This drama cover pretty much everything that could happen to you if you live in this kind of society where people get hurt by society and people around you. The male lead was brilliant, he is so realistic, even though he isn't someone you will see in you real life that easily because this kind of people will get forgotten and overlook from the center of society you live in. I would recommend this drama to mystery drama fan and to those who aren't as well since this drama has a lot of drama and family issue related going on throughout the whole story.
