In "D-day" Cha In Pyo ended up leaving the staff members of the Yong Kwang Fire Department.
On the 18th episode of JTBC Friday/Saturday drama "D-Day" (script Hwang Eun Kyung, director Jang Yong Woo) broadcast on November 14th, Koo Ja Hyuk (played by Cha In Pyo) received a report that Choi Il Sup (played by Kim Sang Ho) who had gone into a joint process with the water pipes of the joint Yeoido area.
The chief of the fire department said, "If you remove the staff members, then the joint area will break because of the water pressure. With that, Yeoido is over too. Honestly, it's too late to take a step back. The burden is to put in more staff members."
At this, Koo Ja Hyuk said, "At times, for a larger goal, there needs to be a sacrifice too. Isn't that right, director?" he started. At this, he said, "We need to get back to our senses. The economy of Korea is under the basement of Yeoido. (The three people that know secrets.) This is a secret that we have to carry to our grave."
Nonetheless, there was a person who ha overheard the conversation with the Fire Department and Koo Ja Hyuk. This was Lee Woo Sung (played by Song Ji Ho).
