Have to say at first it didn’t catch my intention, because when it comes in a drama you want your favorite actor to be the ML. But guess not every drama ML will always be the good and innocent guy, but can also be crazy and mysterious. That’s why I drop this drama when I figure out, but then I decided to give it a try again, this drama got my brain working, and confuse, it’s definitely a crime puzzle that got you solving the mystery. But overall good suspense and killer thrill, that will get your attention
