The Transmigrated Novel Villainess Saves the Grudge-Bearing Father and Son Actors

Lin Ning'an transmigrates into a book. Other people become the heroine; she becomes the wicked supporting female character, the woman married to the second male lead. She is supposed to do every sort of evil deed and meet a gruesome end. The second male lead, Gu Tingbai, and his son, Gu Shiyu, are both thoroughly miserable souls. They resent her because he married the original character and because the heroine once said she admired him. In the end, both father and son meet an unhappy fate, too. Now Lin Ning'an has transmigrated into the story. She has to complete her mission: find Gu Tingbai a good partner and get his son back on track. She plans to take it one step at a time. But as she works on the mission, she eventually finds she can't leave. She's become that partner herself.
