After School took a unique approach for their newest comeback, splitting into two units - 'After School Red' and 'After School Blue' - fostering friendly competition between the members. The famous composer / producer Brave Brothers will collaborate with After School's Kahi, Jungah, Uee, and Nana for After School Red's "In the Night Sky", while After School Blue's Raina, Lizzy, Jooyeon, and E-Young will be working with Jo Young Soo. Earlier today, Pledis Entertainment's official website updated their site with 2 new concept photos of both units, to whip up even more anticipation for their official unveiling next week.
