I love the plot and the cast have a good chemistry, this show is very entertaining. They always bring something new in every episodes. When I watching this show i can rewatch again and again because i love how they're solve the case together and there's a plot twist at the end of episode. The cast have a family chemistry they look so close at each other, this show is very heart warming, especially the older cast always caring the youngest cast just like a they have known for a years. Na PD ideas is out of the box he always bring something new in every veriety show that he made, he's genius. And the cast also genius too.
