Crush and Blush (Hangul: 미쓰 홍당무; RR: Misseu Hongdangmoo literally Miss Hong Dang-moo) is a 2008 South Korean film. It is the debut feature film of director Lee Kyoung-mi, and also the first film to be produced by Park Chan-wook.
Yang Mi-sook is an unpopular and frumpy high school Russian teacher, who has a habit of going red in the face. For ten years she has been harbouring a crush on Seo Jong-cheol, her former teacher and now married colleague, though he is more interested in pretty new teacher Lee Yoo-ri. Mi-sook tries to put a halt to this blossoming romance, forming an unlikely alliance with Jong-cheol's daughter, Jong-hee.
Crush and Blush premiered at the 13th Pusan International Film Festival, which ran from 2–10 October 2008. It went on general release in South Korea from 16 October, where it was ranked second on its opening weekend with 201,414 admissions. As of 16 November it had received a total of 536,980 admissions, and grossed a total of $2,521,251.
Crush and Blush won the awards for Best New Director and Best Screenplay at the 29th Blue Dragon Film Awards.
