In episode 9 of 'Ghost' that aired on the 27th, Park Ki Young (played by So Ji Sub) went to see Nam Sang Won's family. When he arrived, Kwon Hyuk Joo (played by Kwak Do Won) was already there, and the two had erupted in argument.
While Park Ki Young and Kwon Hyuk Joo were driving away, they heard someone's urgent voice on the radio "Se Kang Group is watching all of us". Someone was screaming when the radio was interrupted.
At the same time, Yoo Kang Mi (played by Lee Yeon Hee) went to see Nam Sang Won's driver, Lee Jong Hyun. She heard the same song which was played on the radio. Because of this, Yoo Kang Mi suspected that the driver was connected to the Nam Sang Won murder case.
Park Ki Young asked Kwon Hyuk Joo "Now, it's your turn. Where are you going?". And he also asked him again "Why do I have to tell you the story?"
Kwon Hyuk Joo answered "Same here. If someone were guilty, he must eat beans and rice. I'm going to arrest the criminal. Who do you think he is?" After that, both Park Ki Young and Kwon Hyuk Joo decided to investigate the murder case together.
