Special stages are all lipsynced anyways. And Momo was the only one rapping so why are you comparing her vocalization to???╋╋And if you want to compare, compare her pronunciation with other foreigners instead. It's not just about the pronunciation but their mouth's shape is naturally different so of course they'll have difficulty pronuncing some of the words and it's not like she's not making any effort. So there will still be some lingering accent even though you've been learning Korean for a long time, even though she will surely improve if she continues. Mina debuted not even a year after she started learning Korean and Momo also knows that she's still lacking so she's making a lot of effort.
