'Ghost' So Ji Sub: "I Am Park Ki Young"

Park Ki Young (played by So Ji Sub) has revealed his true identity to Kwon Hyuk Joo (played by Kwak Do Won).

On Wednesday's episode of the SBS Wednesday-Thursday drama 'Ghost', Park Ki Young and Kwon Hyuk Joo open an investigation into the death of Han Young Suk. 

Park Ki Young is in the process of looking for evidence inside Han Young Suk's car at the junkyard when Kwon Hyuk Joo appears with an evidence bag, asking, "Looking for this?" Opening the bag, Park Ki Young finds the photo of Kang Woo Hyun and Jo Hyun Min together.

Kwon Hyuk Joo reveals that detective Han always hid important evidence behind his spare tire, and attacks Park Ki Young, saying "You don't know anything about detective Han, do you?"

Park Ki Young's bombshell announcement comes in response to Kwon Hyuk Joo's angry comment, "Detective Han trusted you, so he didn't show this to me. Why did you kill him?" Park Ki Young then reveals "Woo Hyun is not the criminal. He died in the explosion. I am Park Ki Young."
