During a live broadcast after the concert, they shared the story of how nervous Jaehyun was in giving Jungkook his present and letter.
와개웃겨 보넥도 명재현씨 정국이한테 편지랑 선물 주려고 했는데 너무 긴장해서 선물만 줘버렷대 겨우 편지 전달했는데 멘트가 “그저저저서선배님 저제가 어어렸을때부터 꾹.. >>꾹프<< 엿습니다” ㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋ pic.twitter.com/7XqFqTeRCp

They revealed that, as they were giving each BTS member a gift, Jaehyun ended up only handing over the gift because he was so nervous. He barely managed to give Jungkook the letter. They also added that he was stuttering while trying to tell him that he was a longtime fan of Jungkook.
Fans agreed that he was a true Jungkook fan after seeing him post a video of Jungkook on Weverse!
