Diane Nguyen, a human ghostwriter, a nice, well-reasoned, misunderstood intellectual, and a Vietnamese-Americanthird-wave feminist from Boston who lives with her rich and famous boyfriend (and later husband), former sitcom star Mr. Peanutbutter. She's intelligent and sympathetic. While writing BoJack's memoir, Diane and BoJack initially develop a strong friendship that becomes increasingly awkward and strained after BoJack develops romantic feelings for her. Diane travels to the war-torn Republic of Cordovia to make a difference, but discovers that this life is not for her. Ashamed of returning to her husband, she develops a severe bout of depression, during which she drinks heavily and sleeps disheveled on BoJack's patio furniture. She is able to reconcile her feelings with Mr. Peanutbutter and gets a job at VIM ghostwriting tweets for celebrities. She is subsequently fired from VIM, and is hired to write for a feminist blog.
