Hello, could anyone offer some opinions over my story?

https://www.webnovel.com/book/16759993005135805

It's my attempt at making an isekai. (Sorry for being cliche)

It's about two kids.
One is a servant boy who is trapped and forced to fight for all eternity until someone can free him from his contract while the other is a lost girl trying to find her way home while surviving in this world.

People would comment on every chapter but one day i pressed the "completed" button by accident and suddenly everything went silent.
I also don't mind doing review swaps but i tend to give harsh criticisms though.
