Sareshita Gyakuten Fuufu

Although she doesn't love him anymore, they were supposed to at least live a peaceful married life....

Harumi was tired of her husband's lack of affection, and out of loneliness, she cheated on her marriage, but her affair was easily discovered by her husband.
Her parents disowned her, and she hit rock bottom. However, the day after she stamped their divorce papers, time rewinds back to just before her affair.......? Harumi swears that she won't make the same mistakes again in her new life, but this time, her husband falls into adultery and she becomes the unwanted wife!

Was this not a fresh start, but a sort of punishment?

Harumi won't be cheated on so easily, however, and she waits for the time to take her revenge!
