The Love Hypothesis by Ali Hazelwood

looked between them, clearing her throat. “Sorry, I forgot how
you and Adam know each other.”
A thud—Holden kicking Adam under the table. “You little
shit. You didn’t tell her about our decades-deep history?”
“Just trying to forget.”
“You wish.” Holden turned to grin at her. “We grew up
together.”
She frowned at Adam. “I thought you grew up in Europe?”
Holden waved his hand. “He grew up all over the place.
And so did I, since our parents worked together. Diplomats—
the worst kind of people. But then our families settled in DC.”
He leaned forward. “Guess who went to high school, college,
and grad school together.”
Olive’s eyes widened, and Holden noticed, at least judging
by how he kicked Adam again.
“You really haven’t told her shit. I see you’re still going for
brooding and mysterious.” He rolled his eyes fondly and
looked at me again. “Did Adam tell you that he almost didn’t
graduate high school? He got suspended for punching a guy
who insisted that the Large Hadron Collider would destroy the
planet.”
“Interesting how you’re not mentioning that you got
suspended alongside me for doing the exact same thing.”
Holden ignored him. “My parents were out of the country
on some kind of assignment and briefly forgot that I existed,
so we spent the week at my place playing Final Fantasy—it
was glorious. What about when Adam applied to law school?
He must have told you about that.”
“I never technically applied to law school.”
“Lies. All lies. Did he at least tell you that he was my prom
date? It was phenomenal.”
