F.CUZ's official fanclub posted an update regarding Jinon's health and the promotion due to take place for their 10th Japanese single "Wonder World" that will be released on June 22nd.

To F.CUZ’s fans from F.CUZ’s Official Fanclub.
Thank you for always supporting and loving F.CUZ.
Today we have some very important news for you. Some time ago when Jinon took the Military Manpower Administration’s health exam it was found that his disk herniation has become much worse than what we thought. Not wanting to worry the fans, Jinon has been continuing his activities as an idol while receiving treatment but due to his extreme pain and how his condition has gotten worse, we have come to the decision that he will have to take a break from his activities. Further, as he has to serve in the military he has decided to put all his efforts into treating his condition and to take a re-exam and serve in the military afterwards.
The release of F.CUZ’s 10th since ”Wonder World” on June 22nd.
Jinon has expressed his desire to take part in the events and concerts for the release of the CD but due to his decision we have after much thought decided to put his health first. Therefore all promotions in June will be done by Yejun and Kan alone. We apologize to all the fans who were looking forward to meeting Jinon.
We ask for your understanding.

Poor leader Jinon. Just two members left with Raehyun and Daegun serving in the army right now...
