Lee Hyun-yi, a former model-turned-TV personality, confessed that she was suffering from the disease.
Yang Joon-hyuk, Hong Jin-ho, Lee Hyun-yi, and Shin Sung appeared as guests on JTBC 'Knowing Brothers', which aired on the 22nd.
On this day, Seo Jang-hoon said of Lee Hyun-yi "I've seen Lee Hyun's life for a long time, and he is a very unique person. I sleep when I'm sad or happy. Whether tired or crying, I just sleep. I just sleep and then wake up refreshed in the morning."
In response, Lee Hyun-yi "That's right. I sleep even though I fight with my husband and wife." "I have narcolepsy. I was actually diagnosed at the hospital. I stayed and tested at the medical center for two days, and it was narcolepsy," he confessed.
Lee Hyun-yi then added "It is said to be narcolepsy, which belongs to the top 10% of those diagnosed by doctors." When Shin Seong heard this, he asked "Isn't it possible to fall asleep when recording the broadcast?" and Lee Hyun-yi answered "It has happened."
