Well think about local acts.
Imagine if a local act flopped here, couldnt chart in Hot 100 or BB 200. But then they become super big in Brazil or Germany or Taiwan or India...would you consider the act to be a hitmaker? Would their international achievements supersede their lack of domestic success?
That's what it's like for Kpop groups that make no impact in Korea but succeed elsewhere like in Indonesia, Japan, China or the US.
wbk that Lisa solo is a flop
