I really liked the drama, though it's ending is somehow sad and little bit confusing but it's concept is really good. I overread some comments about its not so satisfied plot and some viewers don't like Inha's death scene but I think it's quite acceptable.. Coz in my opinion (no disrespect to anyone) though Taeoh & Inha planned everything together but Taeoh never planned to do harm or kill anyone... He wanted to be in Kangoh using his mind and his skills but with Inha by his side ...But on the other hand Inha was selfish , cruel & jealous of Taeoh from the beginning but he kept this secret till Taeoh knew it on his own while he was in jail... So it's quite interesting and enjoyable drama to be seen 👍
