Im Ji Myung, later legally changed to Im Joo An, is a South Korean singer, dancer, and former member of WE IN THE ZONE (위인더존; also shortened as WITZ) and TAN (티에이엔). He graduated from Hanlim Entertainment Arts High School and is enrolled in the Applied Music program at the Korea Institute of Arts.

In early 2018, he became part of hip-hop duo JOOAN & ESON (주안엑스이슨; formerly known as HAHN & ESON) and released their mixtape "Bet On Me". Their agency, Freedom City, was too small to provide any further promotional opportunities, so they both moved to Choon Entertainment (춘엔터테인먼트), where they occasionally released more material together.

He then made his debut in May 2019 as WE IN THE ZONE's main dancer and lead vocalist with their first self-titled album. They were managed by Choon Entertainment and had a few comebacks in early 2020. However, due to internal circumstances, the group went inactive, and in January 2021, all the contracts were terminated without further explanation by the agency, resulting in their disbandment.

Months later, he decided to try being an idol one last time and entered the singing survival show "Extreme Debut: Wild Idol", where he finished in 7th place, earning a spot in a new project group called TAN.

He signed a two-and-a-half-year contract with Think Entertainment (생각엔터테인먼트) and re-debuted in March 2022 with their first mini-album "1TAN" as the main vocalist and lead dancer. However, the agency became embroiled in several controversies, and all members ended their contracts in June 2024. A few weeks later, leader Lee Chang Sun announced the group's disbandment.

He enlisted for his mandatory military service on July 1, 2024, and was discharged on December 31, 2025.
