Omolarami Akindiji : A good romance novel is incomplete without conflict. This conflict is, in most instances, made by a villain. The character, as well as the physical attributes of the villain, depends on the role they play in the story.They have to be outright evil people. Your villain could even be a guiltless person who fell in love with the hero or heroine and created a divergence between them. https://www.crunchbase.com/person/omolarami-akindiji
