Since I haven't actually read 'Love Lust and a Millionaire Novel', it's difficult to say exactly who the main characters are. However, based on the title, we can make some assumptions. There is likely to be a millionaire character who is at the center of the story. There may be a female lead who gets involved with this millionaire, and their relationship could be a major focus. There might also be other characters like business associates of the millionaire or friends of the female lead who play important roles in the development of the story. For example, a jealous business rival could add some conflict to the plot, or a loyal friend could offer advice to the female lead about her relationship with the millionaire.
Without having read the novel, we can only speculate. There's bound to be the millionaire figure. He or she might be a self - made entrepreneur or someone who inherited their wealth. Then there could be a love interest, perhaps a person from a different social background who is drawn into the millionaire's world. There may also be a character who represents the temptations of lust, like a glamorous socialite who tries to seduce the millionaire away from the true love interest. Additionally, there could be family members of the millionaire, such as a controlling father or a kind - hearted mother, who have an impact on the millionaire's decisions regarding love and relationships.
