Arnold Grenwich is forbidden territory. There are a million reasons I can’t give in to the magnetic pull between us, but the biggest one? He’s my best friend’s father. Armed with sharp wit and a sarcastic sense of humor, I’ve kept my heart locked behind unbreakable walls, deflecting every stolen glance and tempting word he throws my way. And it works—until it doesn’t. One fateful night, my world shatters, leaving me adrift and utterly alone. Just when I think I’ve lost everything, Arnold steps in—not as the charming adversary I’ve sparred with, but as the savior I never expected. His solution to my chaos is simple, shocking, and impossible to resist: marry him. A single promise to solve everything. But this fragile arrangement comes with one rule—one truth I can’t forget: Arnold Grenwich isn’t mine to hold on to. Or is he?
