The Villainess Tames The Crazed Devil

The Villainess Tames The Crazed Devil summary:

Making a deal with a demon is a small price to pay for a chance to enact revenge on the man who accuses you of having been seduced by one. This is the choice Isabella makes when her father unjustly has her and her mother burned at the stake for being witches. After returning three years into the past, Isabella starts fulfilling her half of the bargain: freeing the demon queen's tragically beautiful son, Kaiden, and unleashing his inner demon. Isabella has one year to avenge her mother's honor, and she'll definitely make good use of her new demon husband.
