It started off really well and stayed true to its genre but the last half wasn't planned out. Its like they had some good ideas but extremely bad execution. The writers were confused and they also confused their audience.

There is nothing new and basically no premise. I'd say characters are well crafted but they couldn't do much as there was no story.

Give it a watch till the 8th episode and then just skip to the last one you will not miss anything major. Even though I rated it low its still entertaining and better than many overrated and popular kdramas ppl watch for nothing.
