JYJ’s Yoochun will not be serving the regular Korean military duty because of the chronic asthma he was born with. Instead, he will be assigned to a public service personnel position to replace his two year mandatory military service. The exact date of his enlistment (with public service) has not been determined yet.
The report was made on May 3 when Yoochun’s agency, CJ-eS Entertainment, said through a press releases that, “Yoochun was diagnosed with chronic asthma in his first physical examination last February. After three more examinations, he received a grade 4, so Yoochun will serve as public service personnel.”
In fact, Yoochun received an enlistment letter that required him to report to military training by May 21. But because of his on-going filming with SBS “Rooftop Prince,” he has been able to postpone his enlistment temporarily.
“We haven’t decided yet on when he will enlist. He will be focusing on his acting in the time being,” his agency said.

But why is he being called to report already? Isn't he like 25-26? I thought they had to join by 28-30? Or something like that...
