In the episode aired Wednesday, May 10 of KBS2 drama, "Queen of Mystery," Yoo Seol-ok joined the civilian profiler organized byWoo Sung-ha and started working together with Ha Wan-seung.
Yoo Seol-ok heard an explanation about the murder case of female college student of Woo Sung-ha. She showed her passion for solving the case saying, "Detective, I really want to catch him!"
Yoo Seol-ok shed a tear while listening to Woo Sung-ha's briefing. He noticed a strange sense and asked for a short break. He asked, "Do you know the victim personally?" she answered yes so he said, "The case involving personal emotions can mislead the judgment. You get out of the case."
Seol-ok felt suspicious of him and asked, "Why don't you tell us the autopsy result? Are you hiding the truth?"
Woo Sung-ha and Yoo Seol-ok conducted psychological warfare but Yoo was told to leave. At that time, Ha Wan-seung came to her saying, "I came to tell you something. It is related to Shinim-dong case."
Yoo Seol-ok said, "you said to help." Ha Wan-seung suggested, "if you bring me the autopsy result then I will give you Shinim-dong case files." Both of them had nothing but was trying to take the other's evidence and get away.
That's how they got their hands again, Yoo Seol-ok began to search for her own way to track the suspect while she was still involved in Ha Wan-seung's team. The two gathered up the clues in each side.
Then, based on the reasoning, they found a place where the killer would have parked a car. She caught a suspicious man and confirmed his face. The suspicious man was a good neighbor of Yoo Seol-ok. She insisted, "This man steals underwears, but he is not the killer."
At that time, Woo Sungp-ha visited this place and said, "Confidentiality has been leaked." He then shows suspicious acts and Yoo Seol-ok said, "Why are you trying to bury the case? You know everything already."
Ha Wan-seung also thought that something is strange with Woo Sung-ha, and Yoo Seol-oksaid, "Who the hell is the killer?"
Ha Wan-seung went back to the neighboring of Seol-ok and pressed him hard. The neighbor confessed, "I saw the murderer when I was stealing underwears."
