In "Last" Yoon Kye Sang found out about all the strategies of Lee Beom Soo.
On the episode of JTBC Friday/Saturday "Last" (script Han Ji Hoon, director Jo Nam Gook) broadcast on September 5th, Jang Tae Ho (played by Yoon Kye Sang) went over to Suh Mi Joo (played by Park Ye Jin). With that, he started asking about the Dae Dong Bio incident and the strategy of Kwak Heung Sam (played by Lee Beom Soo).
On this day, Tae Ho answered a question posed by Mi Joo about the Dae Dong Bio incident that put Mi Joo into the Seoul Station mess. Mi Joo started saying that far before Tae Ho came to Seoul Station, he had been clinging onto the spider web of CEO Kwak. In actuality, the CEO Jung of Daedong Bio had been bought out by CEO Kwak. He had taken back the goods that he had released and was hidden. In actuality, Tae Ho had gone into a strategy that he knew that he was going to fail from the very beginning.
After learning of the entire strategy, Tae Ho said, "It must not be true that he lost $5 million. He took the goods in the middle and left."
