eun-U, who released her debut single "How Can I Live" and "Good Bye" in May, will be coming back with her second single on July 13th.

The second digital single titled "Blah Blah" was released  on July 13th and was written and composed by Choi Hee Chan (2E LOVE), Ahn Hee Sin, Jung Ki Young, and Maljuk Street Musical History. It is an exciting dance track that fits well with summer and its simple melody, that make the song easy to sing along with, and eun-U's cute and refreshing voice makes this song a true masterpiece. Another track titled "One Two Three" is a medium tempo track about a girl counting "one two three", a magic spell that will make the man she has feelings for fall for her.

The music video for her title track "Blah Blah" is based off the movie 'Transformers' and the plot is about the future's singer eun-U, who got her heart stolen by a man she coincidentally met, and her bodyguard robot that transforms into a car at the tap of her hand.
