This drama is totally worth the watch, i didn't know why this wasn't so popular though but the plot of the story really like hook me up in the drama the male protagonist's father, i didn't expect that the killer would turn out to be him. The plot was good also ki joo's acting was really good all the actors and actresses that was a part of this drama did so well you can feel the emotion and the suspense, if you haven't watched my perfect stranger yet then your missing out.
