    it’s a good watch. i thought at first that the sociopath killed those women because of his love/hatred for his mother, his mother left him and became the lady of the night, but the guy said he had the mission to kill those who deserved to die, thus i think that’s the reason he also killed those innocent old people.

    this is the first time i’ve watched a good casting of the young/old characters: yeon ho and moo jin woo, semblance of facial features.

    I just finished watch this drama. It’s good to watch. This is for people who like a detective drama. I love the unique couple shin jae yi and kim sun jae. And as always, choi jin hyuk is soooooo charming. This is not a romantic drama, but I love it. Thanks the drama writer😊👍
