In "Mask" Joo Jin Mo said that in the worst case scenario, he could kill Joo Ji Hoon.
On the 9th episode of SBS Wednesday/Thursday drama "Mask" (script Choi Ho Chul, director Boo Sung Chul, Nam Gun) broadcast on June 25th, Byun Ji Sook (played by Soo Ae) was worried about Choi Min Woo (played by Joo Ji Hoon).
On this day, Choi Min Woo was extremely surprised to see Byun Ji Sook's face when he woke up from a nightmare. Next to him, the flower vase broke, which surprised the family members. They were afraid that Choi Min Woo would do something wrong and strange. At this, Byun Ji Sook explained that this was because of the large bugs.
Afterwards, Professor Kim (played by Joo Jin Mo) spoke with CEO Choi (played by Jun Gook Hwan). He suggested, "I think it's best to focus on the treatment instead." In addition, Professor Kim saw that Byun Ji Sook would be worried about Choi Min Woo. He said to her, "If you stay like this, I don't know what Min Woo will do. He might even kill someone."
Byun Ji Sook said, "No. That's not what Min Woo would do." He asked about the areas in which he could help. Professor Kim said, "Keep eating regularly. Otherwise, there's going to be some really bad things."
