"A bargain for 5 billion marukas."

"Sure enough, it's a bargain."

'Ertha', who is destined to be eaten alive by the male protagonist bargained marriage with him to change fate! I was reincarnated into a rated 19+ male-oriented fantasy novel. As the original story goes, Ertha was eaten alive by the protagonist Zahid, but I can't die like that because I have my little siblings. I offered a deal to the main character who'd eat me up. I'm the target of the proposal, 5 billion Marukas! All I have to do now is run away before the main character gets a chance to eat me. Can I, Ertha, escape from the hands of Zahid, the greatest wizard in the kingdom?

Ertha Arlez is an impoverished purifier looking to provide for her family. Duke Zahid El Callenor is a wealthy and powerful magician looking to cleanse his evil energy. The two seem like a perfect match… except that Zahid is fated to eat Ertha alive! Ertha must keep the duke at arm’s length for her own protection, but the intimate purification process combined with Zahid’s nonstop flirting make that nearly impossible. Can she stave him off and stay alive, or will she be consumed by passion?
