I Became the Protagonist's Sister-in-Law

In the world of stories, where the white moonlight fades, she, Mu Mingtang, is a substitute. Her family shattered, she was adopted by the Jiang family, and then, replacing the missing white moonlight, she became betrothed to Prince Jin, the protagonist. She was always aware that she was merely a replacement, so she suppressed her true self, living as the image of the white moonlight in Prince Jin's imagination. She dared not speak, dared not laugh, content to live as another woman.
