Belle was transported by a transmigration system into a Western fantasy novel about a tragic romance between a monster duke and a human, where she became a crucial side character meant to drive the plot forward. Adhering to the principle of staying far away from the main characters and vowing to be a zero-presence bystander, Belle began her second life in the book's world. Through her own efforts alone, she revived the declining Count Cren family and, without meaning to, shone brilliantly in the world of the story. Unexpectedly, she caught the attention of the ultimate villain boss. Will Belle be able to stay true to her original intentions?
