The white-haired Jasmine wasn't a character from an anime, but a character from a novel," The Founder of the Devil Dao." Jasmine was one of Wei WuXian's good friends. She was a mysterious woman with outstanding medical and magical abilities. In the novel, Molly's identity and background were controversial, and her personality was very unique and loved by readers.
There could be Molly's owner or owners. They are likely important characters as they have a relationship with Molly. Maybe there are also other animals in the neighborhood like cats or other dogs that play a role in the story.
I'm not entirely sure specifically what 'Molly's Game' is about without more context. It could be the story of a person named Molly and some kind of game she is involved in, perhaps a personal game, a sport - related game, or a game in a more abstract sense like a game of life situation.
