They said, "You know how the military allows the soldiers to use their phone at the end of the day now, right? We have a group chat, and XIUMIN, D.O. and us talk every day these days."

He playfully continued, "But now, I just ignore some of his messages. I seriously had no idea that he would message us that often."

He explained, "For instance, when we were selecting our new title track, he was like, 'I think track #3 will be a better one as the title track. But I do think #1 suits you guys better.' He definitely wasn't like that in the past. He's changed after his military enlistment."
