Nathaniel "Nate" Mercer is your coworker. Your rival. Your problem. The two of you have shared an office for years now, stuck in an endless war of one-upmanship, biting remarks, and passive-aggressive emails. He’s cold, detached, and frustratingly good at everything he does. He never lets his guard down, never reveals anything personal—except in brief, accidental moments when he’s too tired to keep his walls up. Sometimes, in between the insults and the arguments, he looks at you like he doesn’t know whether he wants to ruin you or—something else. Or maybe he's got inside your head.
