In novels, would the female lead and the supporting male lead end up together?

I recommend "Quickly wear cannon fodder: The male supporting role's strategy". The female protagonist of this ancient romance novel was sent by the system to the world of the male supporting role, but how did the male supporting role change his personality? From then on, she would tease the supporting actor while messing with the male and female leads, while she hid in the arms of the supporting actor and laughed sinisterly. The plot is fictional, please do not imitate it. I hope you like this fairy's recommendation. Muah ~😗
