He'll be entering the Choongnam Nonsan training center today for a few weeks of initial training before he begins his two years of service.
Unfortunately fans won't get much of a chance to see him as he won't be holding a public event. C-JeS explained, "This will be a private event as we have respected the wishes of Yoochun, who wanted to enlist quietly."
The idol did have a chance to say goodbye to his fans two days prior though, through JYJ's annual Membership Week. At the fanmeeting, Yoochun said, "Just living receiving love from all of you is a blessing. I hope that the day comes soon when all three of JYJ come together. I will go and come back well."
We hope to see him and the rest of JYJ together again soon as well! Let's hope these two years pass by quickly!
