Sunny is a 2011 South Korean comedy-drama film. The film is about a middle-aged woman who tries to fulfill her friend's dying wish of reuniting their group of high school friends. The film alternates between two timelines: the present day where the women are middle-aged, and the 1980s when they were in high school. It is the second film by writer-director Kang Hyeong-cheol, who previously directed Scandal Makers (2008).
