My knowledge is based on data , and I cannot provide information on any events or developments that may have occurred after that date.
However, I can provide some general insights based on how fans and the entertainment industry have reacted to similar situations in the past. When a beloved celebrity like Jungkook, a member of BTS, announces that they are in a serious relationship or getting married, it is not uncommon for fans to have mixed reactions.
Some fans may be happy and supportive of Jungkook's decision, understanding that he has the right to personal happiness and a private life outside of his career. These fans may congratulate him on his relationship and marriage and continue to support him and BTS in their music and endeavors.
On the other hand, there might be a segment of fans who feel disappointed, sad, or even angry about the news. This reaction may stem from a sense of possessiveness or an emotional attachment to the celebrity, which can lead to feelings of loss or jealousy.
In either case, BTS and Jungkook are incredibly popular and successful worldwide, and their fanbase (ARMY) is known for its passionate support. While there may be some initial mixed reactions to such news, it is likely that BTS and Jungkook will continue to have a massive following and enjoy significant success in their music careers.
As celebrities, it's common for BTS members to maintain a balance between their public and private lives. They may choose to share some aspects of their personal life with fans, but they also value their privacy and the ability to have personal relationships outside of the public eye.
Overall, the response to such news would depend on individual fans' reactions, but BTS's talent, hard work, and dedication to their music are likely to be the primary factors in their continued success regardless of any personal developments.
