He needs a wife to save his empire. She needs a miracle to save her sister.

A ruthless CEO, Kim Min-jun, is haunted by a six-year-old ghost and the sins of his father. To save his company from a vicious rival, he needs a quiet, unassuming wife. Lee Na-eun, a struggling artist, is desperate for money to pay for her sister's life-saving treatment. Their solution is a cold, calculated contract: a fake marriage, a public lie, and a perfect, beautiful fairytale for the world to see.

But in the quiet of their shared, desolate penthouse, their lies begin to unravel. An imperfect Christmas tree, a hidden family tragedy, and a shared, profound sorrow become the building blocks of a truth neither of them expected. The contract is a lie, but the trust they build is terrifyingly real. As Min-jun's past and his enemies close in, Na-eun finds herself a silent partner in a war she never chose. The line between what is fake and what is real blurs, and they must decide if the love they found in a lie is worth fighting?and dying?for.
