Purple lilly

There are only few kdramas i have watched where female lead is intelligent and quickwitted from start to end. This is one of them

Good casting. Story is dark and thrilling. But nobody warned me about the sad ending. I wanted a better and happy ending. Female lead was stupid at some instances. And an expert killer doesnt lock his secret door. Seriously. That was so stupid, if that wasn't the case, there wont be strong evidence against him and the ending may have been better
