Tsukishiro Yuina, a singer who lost her voice in a traffic accident, felt hopeless. In her despair, Yuina chose to end her life, but when she opened her eyes, she found herself in the world of a novel she had read before her death, The Saint Who Abandons Her Status.

She had possessed the body of the novel's villainess, Ariadeline. To make matters worse, it was at the point where the main protagonists were already married, and Ariadeline had been condemned.

Even in the world of the novel, her miserable situation didn't improve. Yuina (now Ariadeline) decided to take her own life again, but this time she was stopped by her former husband, Carlothian.

"I don't want you to die."

Even though he was the one who killed her in the original story, Carlothian repeatedly interfered with Ariadeline's attempts to end her life.

"Why won't you kill me like you did in the original story...?"

Thus begins the tale of the villainess who lost her dream, Ariadeline, and her tsundere former husband, Carlothian, as they attempt to redo their misunderstood love story.
