Moon Chae Sol, known simply as Chaesol, is a South Korean singer, dancer, former member of GOOD DAY and current member of CIGNATURE. 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 2017 as part of GOOD DAY with their 1st EP, "All Day Good Day". Months later, she entered the singing survival show "The Uni.T" but was eliminated in the earlier rounds. As she was in the competition alongside 3 other group members, the group was not able to promote and was not successful, so they quietly disbanded as C9 Entertainment began planning their next girl group.

She re-debuted in 2019 with CIGNATURE as their lead vocalist and visual with their 1st single, "Nun Nu Nan Na". Their releases have received positive reviews, describing their music as refreshing and with a unique expression. In August 2023, they came back with their 4th EP, "Us in the Summer".
