I picked this up after I finished Unraveled. This was all right. I quite like the premise of 'boy who is mean to a girl while they are teenagers secretly wants her' and 'mean boy apologizes to girl he was mean to' for Reasons, but Evan spent too much time lusting after Elaine, the time-skip in the middle was weird, and the conclusion was also weird. I read that Courtney Milan wanted to give Elaine a happy ending and that's what this felt like: an imposed happy ending on a character who had started out in a minor supporting role. 
 Mind, I felt like Elaine's core issue: the bathtub scene and the damage she'd done _to herself_ was extremely strong, especially after reading Unraveled. It was a nice contrast and as somebody who has in fact damaged herself in response to external trauma, I empathized. But I don't think as a whole the novella format really worked for this story. It just made it too rushed and too artificial.
