B1A4's CNU wrote to fans from the military.
On February 21, CNU posted a handwritten letter to fans on B1A4's Twitter, talking about his military service and the group's track "A Day of Love", which he composed. His letter is as follows:
BANA, it's CNU. It's been a while since I've called out to you. You're all doing well, right? I'm hearing the latest news online and handwritten letters you've sent me. The things you say give me a lot of strength for my military life. I'm reading each and every one of the many letters you sent me, and I'm working hard in my military life. I'm doing well. I'm doing so well that I wonder if it's even acceptable. I'm enjoying the food and sleeping well, and I get along well with the others in my barracks.
I've also become the company commander for the 10th company! I'm still learning, but I'm trying hard so that I can improve. I heard Sandeul and Gongchan successfully finished the Japanese fan meeting. There were some worries because it was their first performance without me, but those worries weren't necessary. I'm really happy too because I heard the reactions were great, and BANA had a good time.
Oh, you received the gift I sent you, right? Thanks for loving 'A Day of Love' so much. When you're tired, having a hard time, or when you miss us, I hope you'll gain strength by listening to this song.
I'm writing this letter during our free time on the weekend, and I'm thinking about all of you a lot. I'll wait for the day I can meet you again onstage. Until that day, you have to stay healthy! Also, if I have the chance again, I'll send you news about me. It's cold outside, so please be careful not to get sick. I hope that you'll eat regularly. That's all for now. Let's win!"
CNU started his mandatory military enlistment on January 22 KST.
