@Jinflyingkiss i think it’s cus of beauty standards or just because they are all very close to each other and stuff . And China and Japan are really good places for marketing so they try to spread between them
I think their is online auditioning on their website . It depends which company ur going for because I know that on jyp’s website they have online auditioning link but idk about anywhere else
@_jeon_jungcook_ i read this a lot on Google that u can nd even Jin of BTS Irene of Red velvet also debut after 18 (idk the exact date becz I'm into Red velvet that much)
