Im Woong Jae, later legally changed to Yim Si Wan, is a South Korean singer, dancer, actor and member of ZE:A (제국의 아이들). He graduated from Gudeok High School and later obtained an associate's degree in Practical Music from Woosong Information College. He made his debut in January 2010 as the group's vocalist and visual with their first single album, "Nativity". Originally named Child of Empire, Star Empire Entertainment (스타제국) decided to officially establish it as ZE:A. However, they faced immediate controversy as it was very similar to Brown Eyed Girls member JeA. Both agencies began negotiations and agreed that ZE:A's pronunciation will be changed to avoid any confusion. Afterwards, they enjoyed a lot of success and signed with Sony Music for promotional activities in 9 countries, mainly in Southeast Asia, where the group became incredibly popular in a short time. He debuted as an actor in 2012 with a role in the MBC drama "Moon Embracing the Sun" (해를 품은 달) for which he received major praise. He began considering an acting career and he appeared in several other dramas afterwards. His contract with Star Empire expired in January 2017 and rumors began circulating about a possible disbandment. However, the agency and the members released separate statements indicating that the group was now officially on an indefinite hiatus but was not disbanding. He enlisted for his mandatory military service on July 11, 2017 and was discharged on March 27, 2019. After his release, he signed with Plum A&C (플럼에이앤씨) and is focusing on his acting career.
