Jewelry's old members, Seo In Young and Park Jung Ah, have been teaching the upcoming supermodel girl group Nine Muses. Jewelry's company, Star Empire, is the same company that is releasing this new group, so you can look at it as a sunbae-hubae relationship.

Star Empire said, "Park Jung Ah and Seo In Young have been watching these girls since their trainee days, so they've stepped up to be their teachers. They've been helping with training and monitoring their videos." The girls of Nine Muses have been training for 13-15 hours daily since their debut is coming up. Park Jung Ah said, "Their debut is right around the corner. You can achieve your dreams in a little bit, so let's stay strong." Seo In Young said, "Anyone can debut. The important part comes after." They both added, "All nine of them have a lot of talent. They're going to keep working hard after their debut. Please look forward to them." Park Jung Ah and Seo In Young are trustworthy sunbaes, so I'm sure these girls have what it takes.
