Lee Seung Ju, known professionally as Cha Eun Dam, is a South Korean singer, dancer, actress, and former member of A.DE (에이디이). She made her debut in June 2016 (using the stage name Yeorin) as the group's sub-vocalist with their first single, "Strawberry". They were managed by 2Able Company (투에이블 컴퍼니) but were never able to establish themselves in the entertainment industry. The group went on an indefinite hiatus in April 2018, and it is assumed it quietly disbanded shortly after. While some of the members opted to remain part of the company until their contracts expired in 2023, she decided to pay a penalty to terminate her contract with 2Able and left right after the group went on hiatus. She changed her stage name to Cha Eun Dam and announced she was becoming an actress. She had her debut in 2024 with a role in "Queen Woo".
