The connection between Choi Kang-hee and Kwon Sang-woo in "Mystery Queen" finally came out.
On the latest episode of the KBS 2TV drama "Mystery Queen", Ha Wan-seung (Kwon Sang-woo) told Yoo Seol-ok (Choi Kang-hee) that they were connected and gave her the files on the taxi driver murder.
The taxi driver was Yoo Seol-ok's father who wrote a will saying he killed a woman and killed himself with his wife. The woman he killed was Ha Wan-seung's first love Seo Hyeon-soo.
Yoo Seol-ok guessed that the will wasn't written by her father as he didn't arrange his sentences like that. She then found out that the police hid papers involved in the investigation and tried to make it look like murder.
