Yoo Soo-Young (born October 23 1981, Yokohama, Japan), more commonly known as Shoo (her Japanese name), is a Korean singer, actor, and a member of the pop group S.E.S.. Although Korean, she lived in Japan for most of her early life. She got her start in the group by trying out in auditions for SM Entertainment (unlike the other two members, who were discovered through less conventional methods).
