Following their MV teaser released earlier, K-Much debut with their full MV for 'Don't Know Anything'.
At the start of the MV, the boys are dancing into Bar Bar Bar's signature dance moves while wearing their school uniforms and helmets. The transition happens when a sea-like monster electrocuted them and transformed the boys into uniformed fierce looking men.
Crayon Pop's Ellin made special appearance on the MV.
