I'm just a fan of web novels, so I can't provide all the works of Ugly Duckling 2. However, I can tell you some basic information about the novel Ugly Duckling. The Ugly Duckling was a fairy tale novel written by Hans Christian Andersen. It told the story of an ordinary duck who eventually became a swan after being ostracized and bullied. The novel was translated into many languages and was widely welcomed around the world. In addition to Andersen's version, there were many other versions of the Ugly Duckling story, including adapted movies, TV series, comics, and so on. These works usually added or adapted some details from Andersen's stories to meet the needs of different readers.
