I'm a Homebody, but I Transmigrated Into a Dark Captivity Novel

After dying from overwork, a woman is reincarnated as April Salt, a minor character forced to serve the demanding princess. Doomed to another life of endless labor, her fate changes when she is accidentally kidnapped by the undeniably handsome Grand Duke Kaian Braille. Instead of dying again, she is confined in luxury, with every need met. What should be a prison starts feeling like paradise. If only everyone would stop bothering her and let her do nothing!
