They sold 440k already in 3 days. They definitely able to reach more than 700k on the day of release.
They have 4 promoted song. Hype Boy, Attention, Hurt and their title track is definitely going to do well on chart.
200k uls is around 13M on Gaon Chart.
If all of their song reached 300k uls which I think they can get more to that. 20 x 4 = 80M digital a week and if they continue to get over 80M every week then 12 x 80 = 960M digital which is very close to IVE number in just 4 months.
