"Either Way" isn't even their title track, they still have one more song then after that the title track and people are already calling it a flop. A song being number 22 on Melon is not a flop. If I remember correctly same thing happened with Aespa and welcome to my world. People are foaming at the mouth to call groups flops. A CB being successful or not does not just depend on charts but sales, public reception, and other factors. At least wait until the CB is over god damn.
Companies aren't stupid (well not that much) they know slow songs like Either Way and Welcome to my world won't do that well but that's not the point. Not everything is made to do extremely well on charts.
Either Way, the song is doing good. (see what I did there, freaking Jane Austen I tell you).
