Personal life

Yoon Seo-yeon was born in Daejeon, South Korea, on August 6, 2003.[2] Yoon received several recruitment offers from various entertainment agencies in the past, but denied them all as she thought that being a celebrity wasn't for her and continued preparing to retake the CSAT. Yoon watched K-Pop idol performances when she was young and wanted to give it a try but did not have any idol training.[3] When she received the offer from her current agency, she decided to accept the offer, as she had always thought her life was like a 'supporting character' rather than a 'main character', so she was motivated to give it a try.[4]
