This show is amazing, it's one of my favorite variety shows of all time, same with its sequels. I made a list of all of my favorites and it easily makes the top 10. So, first of all, I decided to watch this show because of Running Man's Lee Kwang-Soo and Secretary Kim Park Min-Young, but through watching the show, I've come to love all the cast members and their interactions with each other. Especially Kim Se-Jong, she is amazing, and I've watched a lot of her dramas and variety shows since. Anyways, this a comedy detective show with the main plotline established in the first episode that brings the world into focus, and as they solve cases in each episode, it slowly reveals itself, so if you like comedy detective shows, then please watch this show, you won't regret it :D
