I Will Create the Happy Ending!

Chae-Won a normal Korean office worker who kept doing overtime work, saved the life of a little girl in a road accident on her way home. She died and woke up inside her favorite novel titled: 'There is No Happy Ending!' but not as the female lead but as the villainous Lady Beatrice Gasglow, The Daughter of Duke Gasglow, and the very first person to die in the novel's first arc in which ignites the war between the continent two kingdoms. To avoid dying, chae-won would need to do her best to avoid all red flags to create a happy ending herself!
