This tv show started out so strong, I loved all the characters and the plot. The first season was so good and then after that it went downhill. Season two was awful it was so hard to get through and the main character disappears for like half the episodes. Season three wasn’t as bad but it was still no where near as good as the first. I’m so glad they brought back Lee Eunhyuk but at the same time it was quite pointless and disappointing. The final episode was awful and cleared nothing up. only watch the first season
