Haedam has always been one of the guys—tough, loud, and fiercely loyal—but that identity comes with a sharp price when her childhood first love looks straight through her and slots her firmly into the "friend" category. Devastated but not defeated, she vows to leave her tomboy past behind and reinvent herself entirely before college, swapping battered sneakers for a polished image that no one could possibly overlook. Yet her first day at a new school proves that transformation isn't as simple as changing her wardrobe; a clumsy misstep brands her as a troublemaker before she can even introduce herself, and her carefully laid plans begin to unravel at terrifying speed. Desperate to salvage her reputation, Haedam turns to the last person she wants to owe—her aloof and reluctant neighbor, a boy who seems determined to keep his distance. But he holds the key to fixing her social disaster, and she has no choice but to strike a bargain: his help in exchange for her silence. She agrees to endure their awkward living arrangement without complaint and to guard the secret he guards so fiercely, a secret that explains why he keeps the world at arm's length. As they navigate the suffocating closeness of shared walls and forced cooperation, Haedam begins to realize that the real threat to her new beginning isn't her past reputation or her neighbor's cold shoulder—it's the dangerous, unpredictable pull between them that neither of them saw coming.
