KBS 2TV's 'Music Bank' denied that there were any problems with LABOUM's win.
KBS said, "The ranking every Friday is decided by the sum of all the data from the week before" and confirmed that LABOUM's data was not problematic. 'Music Bank's #1 is decided by 65% digital sales, 5% album sales, 20% broadcast points, and 10% viewer votes. LABOUM was able to win over IU by beating her on album sales.
However, unlike with BTS and IOI's issues in October last year, KBS has not released the data on LABOUM and IU's win.
