I Believe in a Thing Called Love, by Maurene Goo
Review spoiler: this book is a joy from the moment it leaves the gate.
ANYWAY. Desi knows she needs help, so she turns to the Korean dramas that her widower dad is addicted to—and after binging on them for days, she figures out the formula, writes out a list of K Drama Steps to True Love, and she sets out to follow it to the letter. Shenanigans ensue.
By the time I finished reading this book, my face hurt from all of the smiling. I smirked, I giggled, I laughed out loud.
