One woman's life is taken over by her romantic obsessions in this psychological thriller from South Korea. Yang Mi-suk (Gong Hyo-jin) is a socially inept junior high school teacher who, after several years of teaching Russian, has just been given a new position as an English instructor -- a language she can neither read nor write. Yang is in love with fellow faculty member Seo Jong-cheol (Lee Jong-hyeok), but not only is he married to emotionally distant Eun-gyo (Bang Eun-jin), he's having an affair with another teacher, attractive and confident Lee Yu-ri (Hwang Woo-seul-hye). However, Yang refuses to acknowledge that she and Seo will never be together, and when she learns that he and Eun-gyo are planning to divorce, she hatches a scheme that involves getting Seo's daughter Jong-heui (Seo Woo) to help her derail the divorce. Then Yang poisons Lee's mind against her lover through abusive posts on several internet forums. Miss Hong Dang-mu (aka Crush and Blush) was the first feature film from director Lee Kyoung-mi; Park Chan-wook, director of the international hit Oldboy, served as producer. ~ Mark Deming, Rovi
