On the 10th episode of SBS Monday/Tuesday drama "Secret Door" (script Yoon Sun Joo, director Kim Hyung Shik) broadcast on October 21st, Lee Sun knew about the existence of the secret document and started to suspect Yeong Jo (played by Han Suk Kyu).
On this day, Kim Moo (played by Kwak Hee Sung) was caught as the real murderer of Kang Pil Jae. To protect Kim Taek (played by Kim Chang Wan), he made a false testimony that the order to murder came from Chun Seung Se (played by Yoon Suh Hyun).
Lee Sun said, "The person who had ordered the murder is dead and gone so why did you kill Kang Pil Jae?" Kim Moo said, "The document was so valuable that I sought to put it in my hands." As he indirectly hinted at this document and its existence, it added to the tension of the drama.
