Nobody Knows

Young Jin lays her hands on a doll with six wings from a bereaved family member of the serial murder. She thinks that the doll has something to do with the serial killer. Her investigation leads her to New Life Church and a suspect. Meanwhile, Eun Ho sees a man collapse on the street and takes him to the hospital.

Sun Woo asks Eun Ho if anyone at school bullies him, and Eun Ho says no. Eun Ho receives a prize for saving a man who lost consciousness on the street the other day. Meanwhile, Young Jin finds it strange that the 9th victim Im Hee Jung’s cell phone is nowhere found.

Young Jin comes to visit Eun Ho’s patient room to check on him. She finds signs of assault on Eun Ho’s body, and that makes her think it’s a crime. She starts to follow the traces of what Eun Ho did on the day of the fall. Finally, she ends up in an abandoned building. Meanwhile, Sun Woo is certain that Dong Myung knows something about Eun Ho’s fall.
