During the 16th century, Henri II, the King of France, and his queen Catharine of the Medici had seven children who survived infancy (and a couple more who didn't, whose names no one bothered to record).
Their names were Francois, Elizabeth, Claude, Charles, Henri, Marguerite and another Francois.
At that time no one thought about the Duke of Navarre, Henri, becoming the King.
Catherine de Medicis wielded a huge influence over her children. As a result her sons were weak. Her daughters, who married faraway princes, were less affected.
The first son, Francois, became King and died without a heir.
The second son, Charles, became King and died without a heir.
At that time the two remaining sons, Henri and Francois, had no heirs but since the younger Francois was in his twenties a heir could be expected.
Henri became King Henri III, but the younger Francois got involved to some intrigue and died.
So, suddenly, the Duke of Navarre became the closest heir to the French throne.
Catharine de Medicis named the uncle of Henri III, who was a cardinal in some monastery, as Henri's heir and since the cardinal, being a priest, had no heirs he would name someone to succeed the throne, keeping it out of Navarre's hands. However the cardinal also died.
Catharine de Medicis died after it became clear that Navarre would be the next King, The weak willed Henri III, who never really made a single decision without consulting his mother, was suddenly on his own. An assassin ended his confused 7 month rule, and the protestant Duke of Navarre now became Henri IV. (He would later convert to Catholicism later but that is another story.)

As we entered 2023, out of singers who debuted after 2000, only two acts had full concerts in a stadium - BTS and IU, the sworn enemy of KPop.
I had warned that if BTS falls IU would become the most powerful singer of Korea again, leading KPop to its bad old days.
Then Twice and BlackPink had full stadium concerts, making the transition of KPop secure . Or it seemed.
And, lo and behold, now BlackPink may not continue as we know it. This circle of stadium tours might well be its last.
both Txt and Stray Kids are not doing full scale concerts yet. They are doing a concert in the half-scale 'stadium', the BMO, but that's it.
None of the individual BTS members are doing stadium tours. JK might have gotten there but Taylor Swift is waiting to sink him in November.
So , in later half of 2024, only Twice would be doing stadium concerts.
I don't know whether txt or Stray Kinds would do stadium concerts in 2025, but they might. Given the emphasis on tiktok-style music I don't see the 4th gen girl groups doing stadium tours by then.
So, Twice, out of all these acts , continues the tradition of stadium tours in KPop.
JYP gets to laugh last.
If Twice didn't re-sign, there would have been only IU who would be still active and had done a stadium concert remaining in Korea.
Of course if things progressed that far, she might have decided to ditch her habit of writing her own lyrics and jump into Kpop, but at the age of 31 (actually 1,345) that would have been a hard sell for her.
tl.dr. Twice will keep the tradition of KPop stadium concerts in 2024.
