I mean it's hard to know exactly, because October has many releases coming up which may enter the top 10.
Be'o is in a few days, and given his previous strength, I expect him to go well (also he's a hidden wildcard for Artist of the Year that no-one seems to acknowledge).
A general rule of thumb is - the lower and/or sharper the peak, the faster it will fall. So
After Like - 14 - 18 Weeks
Shut Down - 5 - 6 Weeks
Attention - 16-20 Weeks
Pink Venom - 9 - 12 Weeks
Hype Boy - 13 - 18 Weeks
New Jeans have lots of popularity in KR right now. I think their songs are the ones most likely to stubbornly stick around.
Upcoming acts - Be'o, Seulgi, LSF, Idle all have the potential to hit top 10. Be'o's album is absolutely stacked with talent, so I'd be very surprised if he doesn't chart something.
