IU has once again proved that she is the digital queen with 820k ULs in the first 24 hours. Nobody can have such a number except IU.
However, with Rollin' going viral recently, the song has around 600k ULs on Melon right now. IU Lilac right now is at around 670k. Lilac's ULs continue going down just like other songs after their first 24 hours, which is completely normal.
Both songs are expecting to go down in ULs because of the weekend.
What do you think?
