The incident occurred in South Korea when two Chinese female fans traveled there to watch a Tohoshinki (TVXQ) concert. One of the fans was pregnant. After the concert, these two fans hired a car to follow the group. Later, TVXQ members Shim Changmin and Kim Jaejoong entered the women's restroom (due to the men's restroom being out of order). The two fans followed them inside. Subsequently, Changmin inexplicably smashed the cameras of the two Chinese fans (one of whom was pregnant) and even resorted to physical violence. There have been persistent rumors that TVXQ member Shim Changmin is obsessed with gaming and suffers from depression—was he attempting to perform a live-action combat version? The situation was eventually stopped by Kim Jaejoong and security personnel!
