The monster duchess and contract princess side stories

can someone translate the chapters from 21 to 65? I already bought 8 chapters so I can provide you with the novel.
those chapters deal with the duchess's past and are really nice. No need to know the end of the novel to understand them.
I tried to translate it myself with google but it wasn't easy to understand.
If you are interested please contact me!
some pictures of the novel to encourage you
