In "D-Day" Lee Sung Yeol was the worst of being an inconvenience to others.
On the JTBC Friday/Saturday drama "D-Day" (director Jang Yong Woo, script Hwang Eun Kyung) broadcast on October 2nd, intern Ahn Dae Gil (played by Lee Sung Yool) couldn't do anything in front of the patient. With that, he couldn't speak well about it and this caused a great deal of anger form Jung Ddol Mi (played by Jung So Mi).
Dae Gil was very upset that he was the head intern but he was pushed to carry around different things and set to petty things. He was then desperate to be able to see a patient. However, when Jung Ddol Mi finally called, Dae Gil was standing in front of the patient and froze.
Dae Gil was frozen even though he was given simple instructions such as to make sure that the paitent didn't bleed. He tried to touch the patient with his bare hands and his colleague was absolutely surprised. With that, he had to take a pair of surgery gloves but couldn't even put the gloves on. With that, he said, "What are you doing? Are you making kimchi?" and yelled. Ddol Mi and Ddol Mi was upset saying that he would get a hold of their blood vein.
