On September 22, the staff of “Super Star K5” shared an image to their official Twitter page with the caption, “‘Nation’s Younger Sister’ IU recently sent us an adorable message that read, ‘I am so happy that Eun Woo placed in the Top 10. Please continue to give her your support!’ IU and Jung Eun Woo! The both of you, fighting!”
The photo appears to be taken back when IU was a trainee. The two girls smile brightly for the camera with V-signs.
Netizens commented, “I guess IU and Jung Eun Woo are close” and “I heard Jung Eun Woo is a talented singer.”
