A girl named Y/N dies after pulling three all-nighters rereading her favorite romance fantasy novel, The Rose of the Empire. But instead of waking up in heaven, she opens her eyes inside the world of the story itself. The problem? She isn’t the heroine. She isn’t the villainess. She isn’t even an important side character. She becomes Lady Y/N, the daughter of a tiny northern noble family that was never once mentioned in the original novel. She decides she’ll live quietly, far away from the main plot she knows by heart. Because in the original story, the Crown Prince and the Duke both fall for a kind-hearted commoner girl who rises through high society but after a fierce rivalry, the crown prince wins, and she becomes the future empress. Everything is supposed to be finished. Until Y/N realizes she’s not outside the story at all… due to an arranged marriage she is forced to marry the duke.
