He staged a fairytale romance to impress the press?holiday lights, ice skating, matching sweaters. She can't tell where fake ends and real begins.

Kang Jun-seo, a ruthless CEO with a reputation as cold as a Seoul winter, needs a Christmas miracle. Facing a hostile takeover and a scandal painting him as a heartless monster, he hires struggling actress Kim So-min to play his adoring fiancée. The contract is simple: two months of fake romance, one blockbuster role in exchange.

But So-min is no ordinary actress. She's a master of performance, with a fire he can't extinguish. The more she pushes back against his sterile scripts, the more the lines between their roles and their reality begin to blur. A staged kiss turns into a breathless, soul-shattering moment. A hidden family secret turns their fake feud into a real-life war.

As the stakes rise and a dangerous enemy watches from the shadows, Jun-seo and So-min are forced to ask: is this just a performance, or are they falling in love for real? What starts as a business arrangement becomes a battle for their hearts, their families, and a future they never planned. Because in a world built on lies, the truth is the most dangerous?and beautiful?thing of all.
