Catching Feelings

I, Cassidy Ann Putnam, have a crush.
On Elias Amir Carmichael the Third.
The horror.

It started with a bet, and after almost four years of edging herself with hatred, Cassidy can't help but feel attracted to Elias. And that is a problem. No one has ever matched her so well. No one has ever challenged her in a way that engages every part of herself. No one gets her blood as hot as he does when he volleys every insult she throws at him right back at her.
She hates him as much as she wants him.

Cassidy has sunk her claws into me so deeply that I don't know how to get rid of her.
Or if I even want to.

As much as Elias can't stand Cassidy, he respects her. She's smart and driven, and she's a formidable enemy as his main competition in Stanford's engineering program. It's too bad he's wanted her longer than she's hated him.
Their rivalry has always been a challenge they rise to. But within every insufferable exchange, riding close to that line of hate, is their attraction to one another, driving them both insane.
But what would happen if they gave in to the temptation? Would the unexpected, something neither ever considered, surprise them in the end?
