It feel like the transition to the fifth generation is happening in real time

Decline in charting, dating scandal, encore controversy. I'm not talking about Idle, Aespa or Lesserafim. It happened to Red Velvet, Black Pink and Twice before the 4 generation took over. Just in time for groups like SM's ngg, TBL ngg and ILLIT start opening up the 5th generation and become leaders. I'm hoping senior groups give advice to the younger groups, like Twice and Lesserafim on how to deal with the ups and downs of being an idol.
