"Introducing 4Tomorrow, a unique K-pop project group that was formed with a special mission in mind - to donate all proceeds from their debut to charity. This four-member band was a collaboration between Nega Network, Pledis Entertainment, DSP Media and Cube Entertainment, making it a truly one-of-a-kind group. The members include Gain, UEE, Seungyeon, and HyunA, each representing a different company. They made their debut on October 7, 2009 with the catchy single "Tomorrow". One memorable moment for the group was their reunion performance on December 25, 2009 at Music Bank, where they delighted fans with a dance performance and a cover of Baek Ji Young's hit song "My Ear's Candy" alongside Taecyeon. It was a special occasion where they performed under the name Girls 4, showcasing their talent and charisma."
