It WAS amazing, but it did not convert looooads of people to being lifelong Psy fans, or cause them to rush out and buy loads of his albums, etc.
So it’s quite different to the sort of long term success and growth that BTS or other groups have had.
If Abs wants more for Aespa - entirely possible as no-one can predict the future - I’d imagine it’s better to hope for long-term international success rather than being a one or two mega hit group then falling out of people’s minds.
