Review Detail of TengoUnaGranDeuda in last version

First of all, welcome to everyone who decides to give a bit of their time to read my story. I'll shamelessly give myself a review to not only give you an idea of ​​what I'm looking for with the novel but also to set a goal for the quality that I want to achieve. I've written (or at least tried) a few short stories before but they all failed as they didn't convince me, I'm very serious with this trying to give them a satisfying plot and development without sacrificing world-building, the first few chapters may be a bit long but it was a necessary evil, from chapter 5 onwards I will try to keep them to 1500 words for easy and fluent reading. Without further ado, I hope you like the story and comment on everything you like and likewise, what you don't, I'm open to constructive criticism.
