On April 30, the idol shared a handwritten letter via his Instagram, relaying news of his mandatory military enlistment to fans. He said, "It's just that I will be enlisting in the military, as all men need to do in order to fulfill their duties to the country. I'm sorry for delivering such sudden news to Toppklass.. and my heart hurts when I think about the Toppklass who will be sad to hear this news."
While Hojoon left out his exact enlistment period, he assured fans that he will be updating them with a specific address, so that he can receive fan letters of support during his mandatory service. Best of luck to Hojoon during his short time away!
