Author's note:
Hello! Everyone I am the author of this novel. It's my first time trying to write a novel.
SO the writing quality is probably low for now but it will be improved with time and effort. I hope you can help me with pinpointing the grammar, spelling and logic errors to make this story better. I am using Grammarly but it's a basic version and it only shows the basic errors.
I am a university student so I will try to upload as many chapters as I can but for now, I guess the release schedule for this work will be 4 chapters per week.
Also, my naming sense is horrible so every character in this novel will only have a first name.
# Important.
I don't own the cover it's an image Made with PosterMyWall.
Thanks for checking out this novel.
