The Wallflower Who Was Proposed to by the Tyrant

Jisu Kim inherited a peculiar power from her mother: the ability to see and hear ghosts. When an old spirit starts to meddle in her life, she gets transmigrated to a novel she recently read but barely remembers. Now she must live as Fluerty Bebenia, the daughter of a duke. Trapped in the body of a side character doomed to die, Fluerty must use her power to change the novel and ensure her survival. If that means having to marry the handsome, aloof Grand Duke Dever Noctis, then so be it!
