Following the teasing after the end of After School's "Shampoo" MV yesterday, Pledis Entertainment has finally released the concluding chapter with the MV for "Let's Step Up". This MV doesn't have much of a story though as it just shows the girls performing their full tap dance routine after rehearsing and preparing for it in the earlier "Shampoo" MV. Bekah sustained an injury during rehearsals and thus did not participate in the MV filming. Meanwhile, stay tuned for After School's first comeback stage on Music Bank tonight!
