Go Won and Chuu & Go Won are the debut single album sets by Go Won of South Korean girl group LOONA. They were released on January 30, 2018 as the eleventh part of the “Girl of the Month” project.

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


Each unit pursuing their music as independent groups, ‘LOOΠΔ’ realized their idea of becoming one big group with many colors, and now, the eleventh member Go Won appears where Yves and Chuu have met after denying the Garden of Eden.

Yves, Chuu and Go Won will soon meet the last piece of the puzzle to create their own universe of girls who escaped the Garden of Eden.[1]

유닛 마다 하나의 완성된 팀의 형태로 활동을 하는 ‘이달의 소녀’라는 팀은 여러 색깔이 모인 하나의 큰 그룹이 되겠다는 컨셉을 점점 현실화 해 나갔고 정해진 운명에 맞서 에덴을 스스로 거부한 이브가 만난 공간에 11번째 멤버 고원이 등장한다.

이브, 고원. 그리고 마지막 퍼즐이 만들어 갈 이달의 소녀 세계관은 에덴에서 떨어진 소녀들로부터 시작된다.

  • Each album contained an eden green attendance card. If the owner of the album attended a Go Won fansign they would have their card stamped. If they managed to get all twelve attendance cards stamped, one for each member of LOONA, then they would get the opportunity to meet all twelve members of LOONA at LOONAbirth, have their picture taken with one of the girls, and have a mini private concert.
