Chuu and Yves & Chuu are the debut single album sets by Chuu of South Korean girl group LOONA. They were released on December 28, 2017 as the tenth part of the “Girl of the Month” project.

The physical album was sold in two parts: the first album titled Chuu featured Chuu solely, while the second album titled Yves & Chuu featured Chuu alongside Yves.


We all wonder who the last member is going to be. The start of the new unit took off with Yves, and now the tenth member of LOOΠΔ, Chuu, reveals herself to bring a new wind into the universe of LOOΠΔ.

The new single lets the fans take a peek into what JiWoo, who has already been a popular trainee among fans, had to go through to become ‘Chuu’, and her desire to be loved by Yves, who also has said in her lyrics, “my heart that wants to be like you gets colored, filled with you.”

When the four girls who denied the garden of Eden gather, the party begins.[1]

마지막 멤버들을 향한 기대감. 새로운 유닛은 이브를 시작으로 열 번째 멤버 를 등장 시키며 이달의 소녀의 세계관에 새로운 긴장감을 불러일으킨다.

이미 블록베리크리에이티브에 입사하기 전부터 유명 연습생이었던 지우가 되는 과정. 그리고 너처럼 되고 싶던 내 맘이 너로 인해 가득 차 이브에게 사랑을 받고 싶어하는 어린 소녀의 감정을 싱글을 통해 담아냈다.

에덴을 거부한 네 명의 소녀들이 모이면 파티가 시작된다.[2]
