Originally, EXID was scheduled to perform at the concert along with San E, Oh My Girl, Crying Nut, Sweet Sorrow, Insooni, and more. However, the actual citizens of Euijung-bu, where the division is located, suffered highly from the division being located there. The area is in high debt because plans to create a subway line fell apart, but spent millions anyway to hold the concert. The concert was free, meaning that they would not make it back from ticket sales.
Not only so, many citizens protested celebrating the US army division because June 14 is the 15th-year anniversary of two female middle school students Misun and Hyosoon from the area being crushed by a US tank. Not only so, many citizens protests soldiers from the division had committed countless crimes in the past (there are even songs about how the soldiers treated Korean citizens).
Following many requests not to appear, EXID (along with most others) ultimately decided not to come to the concert. Their label apologized and clarified that they had at first agreed to be at the concert, but after finding out what the concert was supposed to be celebrating, ultimately decided not to. Others such as Crying Nut and Insooni came to the concert but did not perform and instead apologized for appearing.
The city said, "The performers did not come to the concert because of the flood of criticism related to a concert being held just days before the 15th year since the Misun-Hyosoon incident. We apologize to the citizens for the concert falling apart."
