A member of a certain idol group is accused of receiving a blackmail from his ex-girlfriend with a "nude" video, and many people are speculating Park Yoo-Chun from JYJ as the central figure of the rumor. An insider of JYJ gave an interview to deny such doubt saying that Yoo-Chun has nothing to do with this rumor and that it is even silly to give a press conference regarding this incident.

This rumor, however, is getting very serious since many are assuming that this video does exist and that there might be even more videos and pictures of this member. Consequently, Park Yoo-Chun's name was bandied frequently about in connection with this scandal. Some are afriad that this scandal might get more serious and that his reputation might be besmirched.
