Story and premise

A handsome, selfish noble falls for a beautiful, kind commoner -- at least, that's how the story's supposed to go. When an average college student wakes up as Cha Sun Chaek, an extra in her favorite romance novel, she resolves to enjoy the luxuries of her character's status while watching the novel's plot unfold from the sidelines.

However, her plans are soon derailed when she finds herself in bed with no other than Lee Bun, the novel's hero! Dodging the villainess' schemes, the Duke's advances, and her own feelings, can Sun Chaek keep the story on track and survive beyond the first night?
