Hayley Cooper has always been the girl who tries to hold her world together-even when it's silently breaking her apart. Engaged to her high school sweetheart, wrapped up in expectations she never asked for, and fighting a growing sense of suffocation, she keeps smiling because that's what everyone wants from her. Everyone except Nate . Nate has been in love with Hayley since the day they met-long before he had any right to be. She was taken, happy, and completely unaware of the way his heart tripped around her. So he did the only thing a decent guy could do: he shoved the feelings down, locked them tight, and chose to be her friend. Her best friend. The one who shows up, every time. But as Hayley's wedding draws closer and the cracks in her perfect engagement begin to show, Nate sees pieces of her she's been hiding from everyone else-fear, doubt, and the quiet ache of a girl who isn't sure she chose the right life. And Hayley starts seeing Nate differently too. Their late-night talks grow heavier. Their silences deepen. Their laughter lingers a little too long. And in the moments she least expects, Hayley feels something she's not supposed to feel: safe. Seen. Wanted in a way she hasn't felt in years. Now, with vows looming and her heart pulling in two different directions, Hayley must confront the truth she's been running from maybe "forever" isn't with the man she's promised everything to... but with the friend who's loved her quietly all along. And Nate must decide whether to step back one last time... or finally fight for the girl who was never his, but might be meant for him.
