Kim Ji Won, known professionally as Zzone, is a South Korean singer, dancer, musician, former member of GOOD DAY (굿데이) and CIGNATURE (시그니처), and current member of LATENCY (레이턴시). She graduated from Deoksu High School, and before debuting, she used to model for Sonyunara, an online fashion shopping portal.

She made her debut in August 2017 as GOOD DAY's vocalist and face of the group 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, center and face of the group with their first single, "Nun Nu Nan Na". Despite receiving positive reviews for their music, C9 Entertainment (C9엔터테인먼트) decided to disband the group in December 2024 after several discussions with each member so they could each pursue their own individual activities.

In January 2026, she re-debuted once again, but now as the guitarist of LATENCY, an all-female rock band managed by Oddinary Records (오디너리 레코즈), with their first single "It Was Love".
