Block B's Jaehyo left a thoughtful handwritten letter for his fans on his official military enlistment day.

Jaehyo enlisted on December 20, and he left a touching letter for fans on Block B's fan cafe to express his thanks for their support. The Block B member's letter is as follows:

"Hello, this is Jaehyo. I didn't think my enlistment would come, but the time is here. I'm only ashamed and filled with regret I couldn't enlist as an active duty soldier because of my knee injury. As I was preparing for various events to meet with fans as much as possible before enlistment, I realized how much I was loved by you guys. I'm thankful enough that you guys shower me with your unconditional love, but I'm even more thankful you would worry about my well-being during my time in the military. I can't stop expressing my gratitude for your love. We won't be able to meet at official events while I'm fulfilling my military duty, but I'll continue to participate in various charity work. The news of my enlistment might have come as sad news especially to our fans who went through a lot, but it's a duty I fulfill as a Korean male citizen. Everyone has to do it, so don't worry too much. I'm currently writing this letter at a hotel near the army base training center in Nonsan, and I have mixed feelings. A part of me realizes this is happening while another part of me still feels like I'm in a dream. I bet you're all wondering how I would look with a shaved head! I haven't gotten my haircut yet. Once I shave it off tomorrow, and it's not looking bad, I'll share with you. The love I received from you guys... I'll work harder and harder to pay it back. And don't worry because I'm able to adjust to new surrounding and make new friends quickly. One thing I'm concerned about is you might forget me if you don't see me for a long time. Please don't forget me. I hope to return as a person with maturity. I bet if someone else read this, they might think I'm enlisting as an active-duty soldier. I want to go to Taeil's concert, which is being held soon, but I'm sad I can't go. I have so much to say right now, but this isn't the end. I'll stop myself from writing any dark or depressing words. I'll continue to post letters and other things during my time in the military if I can! Please take care of our members. If you knew them well, you'd see they're actually very mature and kindhearted. I ate chicken and tofu stew for dinner today. I ate everything I might miss during training, so don't worry. I'll be waiting for the day I can meet with our BBC again! As I'm writing, my feelings are getting more and more complex. I think I'll be serving as a public service worker at the reception center in Seoul. Seoul's tap water Arisu! I'll take care of it. BBC always fills my insides with undeserving love, and I love you. I ask that you stream our members' new music like crazy one it releases!"

Good luck to Jaehyo on his military duties! Stay tuned for updates on Jaehyo and Block B.
