I really like how all two main character interacts. The male despite falling in love with the female lead he still thinks she is the criminal. The criminals in some crimes all seems to be connected to the final crazy guy but it could be just the man is watching her. I really do hate the ending though because I like mystery but I also love romance and its really broad but love can be seen in there just the ending is creepy like most of the other mystery dramas it leaves with a drifter. Like it shows the serial killer kills him selves and it ends. But then it shows someone still writing the criminal post saying will the main characters really be together. It makes a feeling like there is a whole group or another mastermind behind it. What piss me off is that they couldn't show the main characters together even if they had to add another crime in the end to make it interesting at least they completed the mystery and new thing are starting but this one feels like the real criminal has not been found and they still can't be together. I do love it though and wish there will be a season 2. Really hate the feeling of not knowing if they will end together.
