"a North Korean melodrama with a heroine called "the Flower Girl""

"The Little Flower Seller" is a North Korean drama about the anti-Japanese guerrilla movement, accredited to Kim Il-Sung. It is considered one of the “Five Great Revolutionary Operas.” The plot is set during the 1930s, when Japan occupied Korea. It tells the story of a lower class girl who picks flowers to sell, so that she can help her deathly ill mother who is in debt to the landlord.

It was later adapted as a novel, and then a film in 1972.
