I Traveled to a Different World and Turned Out to Be a Supporting Character

By chance, I traveled to a game world that I often play. This is a different continent completely different from the real world, but it doesn't matter, I came with the system! But then I found out that I was actually a supporting role? It doesn't matter, I know the development of the plot, the supporting characters are still popular, the protagonist, just wait a little bit! Then I discovered that I was actually a down-and-out noble? It doesn't matter, I sell milk tea, stockings, cosmetics, chocolate, etc. In another world... And make a lot of money, so I won't be down and out! What, some people say that I am a low-ranking noble and cannot stand on the stage? It doesn't matter, I use money to pave the way, curry favor with the major marquises and counts, and make connections! Nani, are there people saying that I am of low origin and unworthy of my position? In this case, I have no choice but to include the queen of your country in the harem and make you mad...
