Group JYJ's member Yoochun wrote a letter to his fans before going into the army.

On Thursday, agency CJs Entertainment released the letter of Yoochun on their Facebook.

"By the time this letter is published, I'll probably be at the boot camp, right? Hm, may I speak informally? We've known each other for long enough," began Yoochun.

"I didn't have much thought about it for a while but through doing interviews for photo shoots, I finally realized that I'm going into the army, and that I won't be working for a while. And it started hitting me," he said.

He continued, "I knew from a long time ago that around this time I'll be going into the army but when that time actually came, it hadn't hit me. I decided not to be sad about it. I realized more than being sad that there are more things to be thankful for. Thankfully, I received so much love and worked so happily."

Lastly he said, "I'm not very expressive but I just wanted to say that I feel and know all of your love for me. Thank you so much."

On Thursday, Yoochun was admitted into the army for boot camp. He will be serving until May 2017.
