Promises fade with time—days blur into months, months dissolve into years. What happens when the vows you swore become strangers to memory? And what if honoring those forgotten commitments demands everything you have left? Cayne is a billionaire shrouded in contradiction: a charming playboy on the surface, guarded and enigmatic beneath. When his mother demands marriage to a woman of her choosing, he seeks someone willing to play the role of devoted wife—a temporary arrangement for an impossible family obligation. Raszhiel Kein is her opposite in every way. Born into modest circumstances and family turmoil, she radiates an infectious optimism that belies her struggles. Desperate for employment, she accepts an unexpected offer without realizing she's signing up to become a billionaire's contract wife. Their collision course is written in pledges neither expected to keep. Yet as passion ignites and secrets unwind, the lines between performance and reality blur beyond recognition. Will they disentangle themselves from the web of promises binding them together, or will they surrender completely to a love neither saw coming?
