Julian Thorne built his empire on precision and ice. A ruthless CEO who views sentiment as a liability, Julian’s efficiency has finally failed him. To save Thorne Enterprises from a hostile coup, he desperately needs to secure a landmark deal that requires stability, warmth, and commitment—all the "soft variables" he despises. Enter Elena Rosetti, his hyper-competent, utterly indispensable executive assistant. She’s already handed in her resignation, determined to trade spreadsheets for a quiet life with a canvas. To buy her back—and save his legacy—Julian offers her a brutal, undeniable contract: Pose as his fiancée for 90 days, charm New York's elite, and gain the ultimate prize: total, unconditional financial freedom. It’s a strictly commercial transaction with strict rules: separate wings of the penthouse, zero contact outside of public view, and a signed clause that terminates their arrangement the moment the deal closes. But as Elena steps into the spotlight, bringing quiet resolve and unexpected warmth to Julian’s sterile world, their carefully constructed lie begins to feel dangerously real. Julian sees the woman beneath the composure, and Elena finds herself nursing the man behind the machine. In the glittering, perilous height of The Glass Tower, the line between professional duty and burning desire is razor thin. Can two people who treat love like a negotiation survive three months of fake intimacy without losing themselves... or each other?
