Hybe said BTS will perform as one in 2025, but their contracts will end in 2027 (it is not known whether that includes their military services or not.)
But Jungkook appears to have soloist dreams and he can drag it out till 2027. He will be the big factor for BTS continuing as a whole for a long time, especially when the person named at the title of this post might use her influence.
I do not agree with those who think BTS' empire will still be there in 2025. It might be there it will have significantly contracted by that point of time. Some fans will stay loyal, but the days when it was the movers and shakers of the world would be gone.
For the first time since Cho Yongpil, with the debatable exception of SNSD (whose control Iu broke at early 2012), someone has an absolute control over KPop and that is an anti-KPopper who has plotted to destroy KPop for all her life.

There is now a new Korean show named Under the Queen's Umbrella, in which a fictional queen tries to defend the throne for her children, against the Dowager Queen, who has the power to decide the next King, who might have a different mind. It all comes down to the current Queen, played by Kim Hyesoo who is now 53 year old, overcoming the Dowager Queen, played by Kim Haesook who is now 66 years old.
In other words, even at 53 years the reigning queen can't find peace against the dowager queen who was at that position for quite a while.
Something like that happened in Japan, when Empress Michiko, the wife of the previous emperor Heisei, had to fear all the timeher mother-in-law, Empress Kojun, who died in 2000 at the age of 97 (Michiko was from a business family and not from a noble one, and Kojun and her maids looked down on Michiko all the time). Michiko was 66 at the time. However Michiko paid it back to her daughter in law Masako, who doesn't have a son so she can't have a revenge.
In KPop, with the effective end of BTS' control,
Lee JIeun has become the ranking singer of Korean Pop despite of she not being from KPop.
And, because she had the largest concert held in Korea in the 2020s, her power can't really be challenged by those who sell a lot of albums but have smaller concerts.
Although she became the Senior Singer on 2014 because MAMA gave her the Lifetime Achievement Award , she now has obtained the absolute power she craved for all her life. With no one strong enough to challenge her (Laboum effectively disbanded and although its name still will remain it is unlikely that it will ever gain a traction to challenge the ex-owner of Edam), she is going to lead KPop back to its bad old days, and after the afterglow of BTS begins to fade away near the end of 2023, when (if) BTS ever returns in 2025, it will face a much bleaker, and probably a much more isolationist, atmosphere by that time.
