Moon Chae Sol is a South Korean singer, dancer and former member of GOOD DAY (굿데이) and CIGNATURE (시그니처). She graduated from Hanlim Entertainment Arts High School, and before debuting, she used to dance ballet since childhood and spent time as a trainee at Fantagio Entertainment.

She debuted in August 2017 as GOOD DAY's vocalist and visual with their first EP, "All Day Good Day". However, the group was not able to promote and was not successful, so they quietly disbanded in November 2019 as C9 Entertainment (C9엔터테인먼트) began planning their next girl group.

She re-debuted in February 2020 as CIGNATURE's lead vocalist and visual with their first single, "Nun Nu Nan Na".

Despite receiving positive reviews for their music, C9 Entertainment decided to disband the group in December 2024 after several discussions with each member so they could pursue their own individual activities.
