I’m not here to make friends. I’m here to graduate top of my class, get into the best law firm, and make my brother proud. What I’m not here for? Sharing an apartment with Cade freaking West. My brother’s best friend. Tattooed, cocky, insufferable. A walking red flag on skates with a motorcycle named Roxie and a different girl in his bed every night. We don’t get along. We never have—especially not after what happened. He hates me for it. I don’t regret it. I was right. But the longer we’re forced to live under the same roof, the harder it gets to ignore the heat. The tension. The way he looks at me like he’s two seconds from ruining my entire life.

"I want you to take my virginity," I tell my best friend. He chokes on his drink. His eyes go wide, blinking at me like he misheard me. "Dawn." "Not now, obviously. Just promise me you won't let me turn twenty still a virgin," I say, biting my lower lip. He stares at me like I just sprouted two horns. His eyes move slowly across my face. His lips part. He says nothing. "Dawn," he whispers like a plea. For so long, I have loved him. I wanted all my firsts to be his. Instead, I end up in his brother's bed. Killian. I should stay away from him. I shouldn't want him. Not only is he cocky, arrogant — he's the bane of my existence. Yet when he touches me, it feels like I'm the most precious thing in his life.

My best friend had one rule: stay away from my brother. But what he didn't know was that his brother kept me up all night. Wren Mercer had spent years being just Ross's best friend. Fine with holidays at the Calloway house, years of watching Dani, Ross's older brother, move through life like nothing could touch him, fine with the fact that he never once looked at her like she was worth the trouble. So she did what any sensible girl would do, she found someone else. Blake Hendrix was everything that made sense on paper. Charming, attentive, and most importantly, not Dani Calloway. She told herself it was moving on. She told herself it was working. What she didn't know was that Blake had his own reasons for getting close to her, ones that had everything to do with the brother she was trying so hard to forget. When Ross invites her to move into their off-campus apartment, she tells herself it's still fine. She has Blake. She has a plan. Dani barely registers her existence anyway. She can handle proximity. She's wrong. Because Dani does notice her. He always has. What starts as tension becomes stolen moments, a secret neither of them planned, and the slow terrifying realization that this is the most real thing either of them has felt in years. But Ross is right there. Blake is closer than she thinks. And secrets don't stay hidden forever. She fell first. He fell harder. And what breaks between them might not be fixable.

Zayne Bellandi was never supposed to matter. Not as my best friend’s brother, not even as my ex-boyfriend’s best friend. And definitely not like this. He’s dangerous, annoying, untouchable. The kind of man who ruins lives without even trying. But one night blurred every line I swore I’d never cross. Now he looks at me like I already belong to him, like walking away isn’t an option. And maybe it isn’t. Because the more I try to resist him… the more I realized I don’t want to.
