But when the semester started, you introduced him to your vibrant best friend, Sienna—and Julian chose her. Now, a year later, you are trapped in the same friend group, forced to watch them together. But the novelty of Sienna is fading, and Julian's dark, possessive eyes are wandering right back to you. The slow burn is agonizing, the history is deep, and the forbidden tension is about to explode.
