I can't finish this one cause I don't like either of the main leads. And not surprising because while they're on opposite ends of the social ladder they're equally rotten inside and I can't root for either to win.
The first episode was nice from the perspective of a magic show, but once the reveal was there and you figured out how it was done, subsequent episodes don't have the same suspense. In fact, we're bombarded with more rotten temperaments.
It's definitely novel for a KDrama, hence the 3 points, but novelty only gets you so far. For reference I gave up on this mid episode 3.
