The plot definitely moves forward in 6. Don't understand why people feel it didn't. He found out that his uncle is alive. And in Tae Eul's case, she figured that the criminal case she's been working might have something to do with Le Gon world.
I really love the villain role, I can see why they refer to him as a devil. So now we have all our players in place so I feel ep3 will move along with the plot.
I understood the plot a little. The uncle wanted power and he believed that the flute held that power. So he killed his brother to get it. But Lee Gon broke it in half. I think that's what causes the other world to open. Now the uncle met his brother again and killed him. Also, he killed his other half and put it in Corea to let them think that he is dead. And the reason Lee Min Ho is not playing 2 parts is that the uncle killed him so he doesn't exist in the other world.
Qi yue has to be the most selfish character in the show, she's boring and bland that I find my self skipping half the show because of her. She love to blame ansheng for everything yet the latter gave up so much for her.
FYI, its very dark and sexy
