Love all the actors. But the writers did not do justice to the female lead character...she is just so dumb to be a detective. She never got anything right from beginning to end. She absolutely has no wits which makes her a bit boring. And im disappointed with the casting as well,Gu tae su looks so much much older than Auntie Im when it was she who found him when he was a child. That didn't really sit well with me because it makes it too confusing.
Other than that love the sassiness of male lead,gis character is all round interesting and satisfying to watch. Also love the plot twist at the end. I enjoyed this show and I hope you guys do too.
