Seriously disappointed with this show because of how the character's behaviors keep changing too 'illogically!'
For example, the female lead outsmarted the hero brilliantly in first 2 episodes, yet suddenly she is so stupid to trade away the marble (among other silly things ) by episode 6 completely obliviously unlike her nature in first two episodes
The male lead just comes at the behest of his younger brother, and simply allows himself to be taken
there is a lot that is going wrong with this show, despite the high budget and obvious publicity 'push'.
