Hi Zannat I think you have copied someone else's work because your book it is very familiar to the one @crystally_rain wrote.
I get it you like that book so much that you thought why not use it for my book too,but sorry to inform you dear,that story is not an overly cliche trope,so sadly you can't copy it.
Secondly,the book also lacks of proper punctuation and grammar,so I did request you to just take that book down,and maybe after sometime you can write a book which you can actually put copywrite on and call your own,but this one needs to go.
I just hope you don't plagiarize some else's the next time and you know put your own creativity, uniqueness and effort in a book that truly belongs to you.
