(I started this novel in webnovel and it’s my first written novel. Well, now I'm publishing it here after rearranging some details so, it’s not as same as the webnovel version. I'm trying to improve my writing style and as well as the story! Hope you’ll enjoy reading this! And english is not my native language so, you will find blands in grammar and phrases )
