Please Don't Eat Me

"It's five billion Marcas., it's a bargain."
"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!

Ertha 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 brothers.

I offered a deal to the main character who'd eat me up. I'm the target of the proposal, 5 billion Marcas!
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?
