Kim Ha Eun is a South Korean singer, dancer, former member of GOOD DAY (굿데이) and CIGNATURE (시그니처), and current member of LATENCY (레이턴시). She graduated from Pangok High School.

In October 2012, she was part of the pre-debut group LITTLES (리틀즈) and released the OST "Flower" for the drama "The Great Seer". Nega Network (내가네트워크) set their debut date for December 2012, then pushed it back to 2014 and finally cancelled the group in early 2015 without ever releasing any material. She then moved to another agency.

She finally made her debut in August 2017 as GOOD DAY's lead vocalist and lead dancer 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 (using the stage name Ye Ah) as CIGNATURE's main vocalist and lead dancer with their first single, "Nun Nu Nan Na". In April 2021, C9 Entertainment announced she did not renew her contract and that she decided to leave the group without providing a specific reason. She opened a YouTube channel with fellow group mate Hwang Ji Won (previously known as Sunn), but the channel has not uploaded any material.

She was also part of the pre-debut group ALDL (알록달록), but they disbanded in January 2023 without ever debuting.
She became a YouTuber with her boyfriend for a few years before re-debuting once again in January 2026, now as the keyboardist of LATENCY, an all-female rock band managed by Oddinary Records (오디너리 레코즈), with their first single, "It Was Love".
