On the December 10th broadcast of the KBS2 talk show 'Do Dream', the Wonder Girls' power vocal Ye Eun reflected on the difficulties of juggling trainee practice with school life back in her trainee days. Ye Eun, who has been known to have been a top-notch student throughout high school, shared the stress and difficulties she encountered as a student during dance practice. "Dance practice was difficult for me during my days as a trainee. When I was occupied with dance practice and didn't have time to study, I still managed to do well in school and maintain good grades," she revealed. "However, soon after our debut, my situation reversed." Though she was doing well in school without extra hours of studying, Ye Eun struggled with being on top of choreography. Despite working hard, her moves weren't as flawless as her fellow dancers. Ye Eun shared, "I still practiced often, harder and longer than others, but I still lacked in comparison. ... Although it was initially frustrating, I began to realize that, as you yearn for things you want, the joy you feel when you finally achieve those things is on a whole new level." On this episode of 'Do Dream', fellow Wonder Girls member Sohee also shared her academic aspirations, revealing that she was interested in studying film at an American university.
