The veil of "Secret Document 98" was revealed.
On the 8th episode of SBS Wednesday/Thursday "Three Days" broadcast on March 27th, Han Tae Kyung (played by Park Yoo Chun) gave a resignation letter in the bodyguard room and decided to carry out the investigation alone.
On this day, Han Tae Kyung tried to open "Secret document 98" on his father's computer. He put in the dates of the Yangjinri incident in the password of "secret document 98" and the password fit perfectly.
Han Ki Joon mentioned that the person who told him about the Yangjinri incident was Ri Chul Kyu (played by Jang Dong Jik) and time went back to when Han Ki Joon (played by Lee Dae Yeon) and Ri Chul Kyu met.
Ri Chul Kyu went to the Han Ki Joon of the past and said, "Now, there will be a great purging. The only person to trust is head Han Ki Joon alone. I don't have time. Do you remember the $10 million you delivered" and talked about the exile.
At this, Han Ki Joon asked whether that money was for food support and Ri Chul Kyu said, "That money was an advance. This was the price of those who had died. That was the secret plan of the Yanks and the South Korean government. It was a transaction for tons and tons of money" and gave a newspaper article about the Yangjinri incident.
Then, Han Ki Joon grabbed Ri Chul Kyu and Ri Chul Kyu said, "I will call you again in a month. At that time, I will bring the words that will prove what I said" and left the scene.
