Jang Keun-suk
In 2010, Moon starred in "Cinderella's Sister", a modern fairy tale retelling of the contentious relationship between two stepsisters (opposite Seo Woo). Later in the year, she starred in the romantic comedy "Mary Stayed Out All Night" alongside Jang Keun-suk. 2010 also marked the year she made her theater debut, in the Korean staging of Patrick Marber's play "Closer". She caused a stir as the strip dancing, promiscuous Alice, opposite Um Ki-joon's Dan.
