Kim Yoon-hye (born May 24, 1991) is a South Korean actress. She first appeared on a 2002 magazine cover of Vogue Girl Korea, and also modeled for MTV Asia in 2005 before starring in several music videos. Kim made her acting debut under the stage name Woori, which means “us” in Korean, making it difficult for her name to be searched on internet portals. She reverted to using her real name Kim Yoon-hye during the promotions for horror-comedy film Ghost Sweepers in 2012. Kim next starred in the TV dramas Heartstrings, I Need a Fairy (also known as Sent from Heaven), and Flower Boys Next Door. In 2013, she garnered positive reviews for her portrayal of a cold and aloof high school girl in romantic thriller Steel Cold Winter.
