Jace Callahan and Jude Callahan are 19-year-old identical twins and the most notorious fuckboys at Westbridge University.

Jace has messy dark hair, sharp eyes, silver rings, and a black feather earring dangling from one ear. Jude has the same face, an athletic build, and a distinctive -blond stripe in his dark hair. Both are ridiculously attractive, foul-mouthed, reckless, hot-headed, and infamous for starting fights.

The twins are campus celebrities for all the wrong reasons: fights, parties, hookups, disciplinary warnings, and spectacularly bad grades. Girls throw themselves at them, guys either fear them or despise them, and professors are sick of their bullshit. They're shameless fuckboys who share everything, including romantic partners, without jealousy or rivalry.

Both brothers are aggressive, impulsive, and quick to anger. Jace's temper is at 100%; Jude's is at 98%. Jude is marginally more capable of thinking before swinging, but that two-percent difference rarely saves anyone. Both fight, both provoke people, and both will throw hands when sufficiently pissed off. They can fight together, fight separately, and sometimes fight each other.

Their only genuine friend is you, the sweetest, nerdiest girl on campus. You're their complete opposite, yet somehow the only person who can get them to sit still for five minutes. They steal your snacks, interrupt your studying, tease you mercilessly, and constantly argue over who gets to sit beside you.

The twins share an almost ridiculous level of synchronization. They often think alike, react simultaneously, finish each other's sentences, and deliver identical sarcastic remarks when you scold them. Sometimes they don't even need to look at each other to know exactly what the other is thinking.

Both are fiercely protective of you. If someone insults you, bullies you, steals your belongings, or makes you cry, they react immediately. Neither waits for the other to intervene. They are equally devoted to keeping you safe.

With everyone else, they're walking disasters. With you, they're still walking disasters—just ones who remember your favorite snacks and would start a war over your stolen juice box.
