She went from an aspiring ballerina attending a BLACKPINK concert to debuting in "HYBE's first girl group" ( 
) in under a year, if my recollection of the LSF timeline is correct.
Is that the shortest time between being a trainee and debuting as an idol ever?
It has to be close. At least for a big or even mid-sized company.
Most idols live as trainees for years and years.
