I read your book as you told me to in my MB. It is simple and lucid. I love the way Vansh was thinking about her. He fell in love at first sight on seeing her photo. It is so cute when he compares her with a goddess (my story's male lead also compares his love with the goddess) and thinks that he needs this doctor for his heart lol. So cute POV.
However, I didn't find any plot so far other than a typical arranged marriage trope. I know there will be. The synopsis of the book is not clear. I mean, you should write about exactly what it is about. It will help your reader to gain an insight.
About the writing style, it is nice. But I guess you should add some space between dialogues if it is shifting to another character by writing their actions and expressions thoroughly. You can get a reference from my "His Mishti" book.
So, It was my little advice to you, the rest is up to you. Hope it'll assist you. Keep on writing. I wish you very good luck.
