It signifies CLC's music transformation as a complete 7-member group, with former Produce 101 contestant, Kwon Eun-bin, finally joining them with promotions.

[15] "No Oh Oh" is a dance number made of simple minor codes and sounds full of twists with a strongly addictive rich-sound chorus.

"It's Too Late" is a ballad song, with the elements of rock music, about the story of a girl who sends a message to her loved one that she no longer cares for him.

[21] On June 17, member Eunbin was unable to attend a fansign event, and announced that she would be temporarily halting group promotions due to health issues.
