Davichi's Kang Min-kyung broke off tune while performing on the debut stage of rookie group Speed.

She went on stage with Speed for their songs "Sad Promise" and "It's Over". She broke off tune during "Sad Promise".

Apparently she apologized to the member when they came down from the stage.

She was going to buy them dinner and encouraged them but she cancelled it because she felt really bad.
