intro
A nice beginning.
You know, you didn't have to write their names in brackets. You could write, 'In which young adult girl named Faiha meets three Korean guys, Park Jimin, Kim Taehyung, and Jeon Jungkook . . .'chapter 1
Didn't anyone ever tell you that when another person says something it always goes to the next line? It's like a new paragraph.
In books, numerals are not appropriate.Back at it again with the grammar mistakes.
chapter 2
I like how confident she is.
Try writing in one tense. I noticed that you sometimes switch to the past tense.
overall
I know for sure that it's a good book, but it would be an even better book if you correct your grammatical errors and recheck the chapters for any other mistakes. You can also use this great app called Grammarly. It will definitely help you.
