Dr. Han Jihoon, a brilliant and guarded surgeon, needs a fianc e to fend off his family's matchmaking. Lee Minjung, an artist with a failing family gallery, needs a miracle. Their solution: a six-month contract and a five-carat fake diamond.
But as they navigate Seoul's high-stakes society, their choreographed lies begin to feel a little too real. With his mother's suspicions, a jealous ex's return, and a family secret threatening to unravel everything, Jihoon and Minjung find themselves in a game where the fake ring is a shield, but the feelings-and the danger-are very, very real.
