Usually groups\/soloists don't last that long but there are some that maintain consistent success like the IU, Rain, Lee hyori, Suzy types. Their popularity hasn't dipped much in sk.\n\nThis can include cf queens, actors, actresses, soloists. Anyone. Just those who are still active and maintain somewhat the same level of success.\n\nThe same goes for idols who you think might have the same longevity.\n\nFor me off the top of my head in sk I feel maybe it girls\/cf queens like Jennie\/hwasa or it boys like bts maknae line or kang daniel or actor\/actresses like eunwoo or jisoo or maybe the soloists\/actors\/actresses that will emerge from twice, bp or bts(if they choose to be) might be a safe bet. There's demand for these 3, especially bts but it's wholly upto the idols if they want to pursue it or not.
