The protagonist has been reincarnated into a romance novel she knows well, including its spinoffs, as a doomed villainess—specifically, a princess betrothed to the crown prince. To avoid her tragic fate, she attempts to alter the story’s course. Soon after, her father unexpectedly presents an engagement letter from the Northern Grand Duke rather than the crown prince. The Northern Grand Duke, who is the original story’s male lead, appears in person and expresses his affection, vowing to win her over. His presence and advances complicate her plans.
