I don't think you understand. Yeah, Lilac may soon get overtook #1 Melon in melon again. However, just look at how IU charting with their b-side and her title track?
820k ULs for 24 hours and 9/10 are IU with the first 24 hours. Which group and artist can do that??
Non can can even reach 820k and most of their b-side can't even chart as high as IU. Like IU b-side chart better than most of the group out there so I don't see where is the downfall of IU.
