Yoon Sun Hee used to be a trainee for years at Jellyfish entertainment. When nothing looked bright for the girl group to debut, eventually all of her group fell apart leaving Sun Hee be the only one still in the company, and the company had no plans of letting her debut as a soloist. As she was told that her times as a trainee were over, she was asked to stay and teach the younger girls interested in dancing and who would have the potential to be the next debuting group if their recent group ever grew. Yoon Hee accepted this, she was close to the age that it would be impossible for her to debut as a singer and now just did choreographys for others. 

VIXX was the only promoting group of the entertainment Sun Hee was in, and it hadn't been long since they had hit the jackpot with their latest album. They were asked to perform at a movie festival, which the company approved and now VIXX had to promote and practice at the same time. 

Sun Hee and Hakyeon used to be trainees together for a while, but drifting apart after Hakyeon got to debut and they lost connection. Sun Hee lost pretty much all contact with VIXX after their debut, so where will this project of preparing for the performance take them to.
