T/N: The original tittle is changed (Related to Boy band TEEN TOP) and also we omitted Information not related to JYJ.
‘Sasaeng fans’ is a newly-coined word for fans who follow a celebrity’s private life all the time. Generally, they follow every trivial move that their favourite celebrity, usually an idol star make. They give up their personal life and follow the celebrity’s schedule. Stalking violates the celebrity’s personal rights and harm the mental health of obsessed teenagers who have yet to develop their personalities, causing societal problems. Actually, JYJ’s Kim Jaejoong and Park Yoochun, Jang Geuk Suk and B2ST’s Yang Yoseob experienced the violation of their personal rights and felt uneasy in their own neighbourhood. They were unable to tolerate any longer so they left a warning to sasaeng fans on Twitter.
