NU’EST W has released “Let Me Out,” their OST for the highly-anticipated tvN drama “Hwayugi.”

“Hwayugi” is a modern retelling of the classic novel “Journey to the West.” The script was written by the Hong Sisters and features a cast that includes Lee Seung Gi, Cha Seung Won, Oh Yeon Seo, and FTISLAND’s Lee Hong Ki.

The drama has teamed up with NU’EST W to release their first OST titled “Let Me Out.” The song has a strong rock sound and dubstep elements with a Complextro base that mix perfectly with NU’EST W’s voices. Leader JR participated in the rap-making of the song and this is NU’EST W’s first-ever OST, making the strong extra special for fans of both the singers and the drama.
