Ifans don't want to admit it but ifans are less loyal than kfans. They will hopping to the latest trendy groups therefore i don't get ot if company pushing the group to international market instead of korean market because they will fall harder later when new trendy groups comes in.
as if koreans are loyal lol. Most of taeyeon's listeners are from general public not from her fans that's why her gp friendly songs are on top of melon while her previous releases tanked.
