I found this psychological drama to be confusing - who was who - the sister, the younger sister, the baby is being called a sister, who was the side kick guy, etc. Even the explanations at the end seemed to be so confusing to me that I fell asleep twice on the last ending episode and had to start it over. I still gave it a 7 for the beginning parts which were a little more intriguing and interesting as the storyline is being established and revenge all started but then the female lead got to be too dislikable. I liked that it is only 7 short episodes so you can finish it on one evening. Japanese Drama that had a little romance in the beginning.
