As a Passerby, I Became a Vicious Female Supporting Character

I became a passerby through books, but it seems that I am not anymore. I feel like I've upgraded to a vicious female supporting role. However, the male protagonist doesn't like me, and neither does the female protagonist. As it happens, I don't like them either. —————— As an early contrasting role for the heroine in the book. The early heroine was poor, her family was heavily in debt, and her life was in embarrassment. I am here to highlight the pitiful existence of the heroine, who is rich and beautiful, has a prosperous and harmonious family, and lives a smooth life. So I'm very satisfied and enjoy it very much. I only appear in the novel in the early stages, and the scene is at best the bar where the heroine works. So the heroine and I are in sharp contrast. I am the consumer, and the hostess is the server; I am the drinker, and the hostess is the pourer. That's all. But now I don't like going to bars, so I don't go to bars. I also don't want to have any contact with the male and female protagonists of this world. So on the night when I was supposed to go to the bar, I ran to my family's hot spring resort in the suburbs. But for me who didn't follow the plot, a butterfly effect occurred. Purpose: To provide readers with enjoyable sand sculpture works
