Park Jimin... CEO of Park Corporations. Cold, powerful, and unreadable. To the world, he's a man who has everything... money, power, respect. But behind the grand walls of his mansion, his life is nothing but quiet misery. His wife, Min Yoonji, was never the woman he chose. Their marriage was arranged by his father... a union built on duty, not love. To him, she's a responsibility. To her, he's a stranger who shares her name but not her heart. They have two children... Jihoon, a five-year-old who hasn't spoken a single word since birth, and Minjun, lovingly called Minnie or Junnie, the sunshine of the family. Jimin loves his kids deeply, but his wife remains a ghost in his life... someone he sees, touches, but never truly feels. Yoonji endures it all... his coldness, his silence, his mother's cruelty... for the sake of her children. But the walls she's built around her heart begin to crumble when buried secrets from their past start to surface. The night that bound them together was never what it seemed. And when the truth unfolds, Jimin realizes that the woman he treated like a shadow was the only light he ever had.
