I can’t tell you why I liked this book as much as I did. I can’t even recommend it with my whole chest to anyone.
I both get and don’t get the Sally Rooney cult following. 

I disliked the characters, they frustrated me. There was this ongoing Will they-Won’t They potential dangling in front of me, so close yet, almost impossible. 
There is no plot, just vibes. So tell me why I couldn’t wait to pick it up, why I enjoyed reading about these unlikable characters so much? 
This book is weird, but I guess in a twisted way- a kind of Weird that worked for me.
The one answer I have and what makes this book unique is how it reveals a person’s inner most thoughts and feelings, how it reflects and discusses the human experience with such delicacy, and how raw and honest it was to the point of literal intimacy.
I’ve never read anything like this, and I can’t wait to read another Sally Rooney book.
