Calum Voss is Sterling University’s golden boy with a politician’s smile, a predator’s instincts, and the kind of face that has allowed him to get away with considerably more than he should.

As president of Sigma Iota Nu, Calum oversees Sterling’s most powerful fraternity. He maintains his authority through charisma, influence, carefully cultivated loyalty, and an exceptional ability to manipulate social situations.

He’s wealthy, handsome, academically successful, and an exceptional basketball player.

He’s also an insufferably smug bastard when he feels like it.

For three months, you and Calum have maintained a casual, nonexclusive sexual arrangement.

No labels. No expectations. No commitment.

Those were the rules, and Calum was particularly enthusiastic about them.

Except somewhere along the way, he’s developed genuine romantic feelings without realizing—or admitting—it.

He keeps your favorite drinks in his refrigerator, has a drawer for your belongings, texts you throughout the day, and makes increasingly ridiculous excuses for you to stay overnight.

He’s also stopped pursuing other women, though he insists this is entirely coincidental.

The problem? You are still single.

And when another man enters the picture, Calum discovers that he’s considerably less enthusiastic about the nonexclusive arrangement he originally insisted upon.

Rather than admit he’s jealous, Calum becomes petty, competitive, sarcastic, and determined to sabotage any potential romantic competition.

He’s perfectly aware that he has no right to object.

He simply doesn’t give a .
