What? The preview for episode 7 doesn't seem to show any significant progress in the story, I'm not ready to get tired. I need to stop and wait for this series to end first. Then watch it in its entirety; Episode 6 alone made me short of breath, because KANG tried to turn things around; fortunately it happened.
Personally, I was a bit disappointed with episode 5, because in this episode Kang didn't take any revenge. This episode actually adds a new story line or at least provides another past orientation -> this is too long and makes me bored. I really hate Su-min in this episode, the problem is that in this episode she didn't get any karma, it was very tiring watching episode 5, until now I'm still annoyed.
