It makes me sad giving this drama "6" , but I just have to at the beginning it was very very promising I even give the 1st 2 episodes a "10", but then the twists are so tighten that they have to solve them in a very stupid way for example that grandpa detective who knows all the answers even if there's no real evidence also making such pure evil characters is not good considering such a character suffered alot and deserves some happiness too The cast is actually doing there best to make a good drama but just the story line is not helping them not forgetting the kids and their adorable acting. I'm preparing my self for a stupid rushed and unreasonable ending just watch it if you have some free time not if you want to enjoy a wonderful drama.
