At this, Kim Do Jin said, "Who said such nonsense? Was it the president? The director will gain much more than money. Where will be use that money? As Lee Dong Whee did, the director will be like this. Not like the secretary but in a new identity. So please give me that object."
At Kim Do Jin's words, Kim Do Jin handed over the USB and as he left, Kim Do Jin ordered his subordinates to kill Shin Kyu Jin. Shin Kyu Jin was stabbed and sent to the special prosecutor Choi Ji Hoon and handed over the 'secret document 98" and died.
