When a side character ends up in bed with the male lead, can everyone still live happily ever after?

When an ordinary college student wakes up as Ripley de Liverpool, a minor character in a romance novel, she's more than happy to live the luxurious life of a noble extra and watch her favorite book play out before her eyes. But after an innocent, drunken one-night stand gone wrong, Ripley finds herself locked in a precarious game of romance with Duke Zeronis de Inglid, the dangerously handsome and obsessive male lead. Anxious to steer the plot back on track, Ripley befriends the original protagonist Etoile and tries to recreate the novel's ending by force.

Unfortunately, the novel's scheming villainess, Rose, and exceedingly attractive second male lead, Wright―not to mention the possessive duke himself―aren't going to let Ripley change the story so easily! Can Ripley convince the original protagonists that they're meant to be? Or is that really how Ripley wants the story to end?
