In "Mask" Yeon Jung Hoon killed Jo Han Sun. Afterwards, he framed Ho Ya for this crime.
On the episode of SBS Wednesday/Thursday drama "Mask" broadcast on June 24th, Min Suk Hoon (played by Jo Han Sun) had killed Jung Tae (played by Jo Han Sun). Instead of confessing to the guilt, he put the blame on Ji Sook (played by Soo Ae)'s younger sibling Ji Hyuk (played by Ho Ya).
Suk Hoon had killed Jung Tae with medication. The reason was that Jung Tae had found out the identity of Ji Sook. Afterwards, he made Ji Hyuk come to the scene where he was lured by a loan sharp. Ji Hyuk didn't even know that Jung Tae had already been killed. He was going to give him medicine and at the end of the day, gave up on trying to kill a person.
Ji Sook had assumed that Suk Hoon killed Jung Tae. Nonetheless, Suk Hoon said, "It could be that you had killed your own sibling" showing the syringe in his hand. At this moment, Suk Hoon pressured her. He said, "There must be evidence that your sibling went to the officetel of Kim Jung Tae. Do you want me to give that evidence to the police?" In a situation where Ji Hyuk could be completely framed for the murder, Ji Sook had no choice but to follow these words of Suk Hoon.
