The Words: An Enemies-to-Lovers Standalone Romance

OMFG this book is so underrated I don't even know where to start.
676 pages of IDK what eff just happened scenes..

I thought this would just be a casual read but my god, while it isn't the greatest writing I've read from an author the storyline itself is worth the 4 stars.
I don't understand though why this is considered a stand alone because this should be a series the ending alone isn't enough as its such a cliff hanger...
