Hello everyone, before we begin, I'd like to clarify that English is not my first language, and this is my first novel, so there may be mistakes (but I'm working on improving). Additionally, the early chapters are short, but as I became more accustomed to writing, the number of words per chapter increased, so you don't need to worry about all chapters being short.
I primarily publish on the Webnovel site (application), so there might be a difference of one or two chapters between the two sites.
I believe that's all, happy reading!
