What is the best way to arrange a mini-menu?

Question

Design

I am writing a website for a writer. As planned, there is a bar on the right, and works on the left. And depending on the selected work on the right, the content on the left changes. Can you tell me how to make this look better?
Maybe you have seen a similar feature?
From the point of view of the code, everything is implemented, the question is in the design.

Answer 1

Are you making a website for money? Looking for a designer. For money. Do it "on enthusiasm", look for someone from your circle of friends who can help you for free.

Answer 2

Do as on this site - on a toaster (just change the fonts-colors). It is better to place the menu on the left so that the text of the story itself does not start at the edge of the screen.
