Blog Layout Issue

Hi all,

I have created a new page titled Book-Notes. In that page, I added some custom code basically an anchor tage with a link, which leads to a particualr post about the book and the notes I have taken. Issue is, I would like it to just post under the Book-notes page and not the main or home page as an article.

Any tips on how to structure this correctly? Link: https://paolotrulli.com
