After episode 6 cliffhanger, the viewers are eager to know more about Park Jung-woo's prison mate Lee Sung-gyu, who admitted his role in Wolha-dong murder case.

The male protagonist was feeling guilty after his own confession about killing his wife Yoon Ji-soo and their daughter Park Ha-yeon during the second trail. So he decided to take his own life in prison at night.

But before he could hang himself to death, he heard the voice of Kim Min-seok's character saying, "Why would you kill yourself? You did not do it. I did it. It was me." When the former defence attorney refused to believe him, he recited a poem that Ha-yeon used to sing often.

The Korean mini-series also featured a telephonic conversation between Cha Min-ho and Kim Seok towards the end of the sixth episode. It showed the latter informing the former, "I found him. He did something wrong and was put in prison." What could be the relationship between the young prisoner and the male antagonist?
