Well some may have counted her out too soon after the not so great weekend uls lol. But after that the song started rising.
Also i feel this ul discussion is going no where. Rosé debuted with big uls because of massive hype. People were waiting for her for a long time + bp got the #1 gg crown. Also stop with ul decrease excuse lol. Nayeon if she had debuted at same time would never cross 400k in 24hrs. She would max do a 250k in 2021 on debut day. But it doesn't matter because POP will most probably surpass 300k uls and come close. Irrespective of uls it'll be the bigger song most probably
