Junjin revealed suffering from panic disorder.
On the episode of Win Win that was broadcast on the 20th, JunJin mentioned that he had suffered from panic disorder during a period of time and had really went throught a difficult time.
JunJin said "During the 4th album, I felt that no matter how hard I tried, people would always view me differently. There were also problems at home and financially. There were around 2 months where I would just lit candles at home and not step out of the house. I would order food but I would not eat them, only drinking soju. That was how I lived."
He continued "I would be thinking and worrying about a lot of things. For instance, I cant see clearly with one of my eye, I would be worrying if the other eye would also worsen. I would be thinking if anyone would suddenly appear and harm me when I am in the car."
"It is not totally cured yet."
