Hellfire Oasis

Yerim and Seulgi, the best of friends/sisters who grew up together, loved to con older men and women with their attractive looks. They were both naughty and mischievous.

One day, they were involved in a car accident, resulting in their deaths.

When they woke up, they found themselves in hell, but surprisingly, it looked more like a paradise than a hellish place.

To embark on their adventure, they encountered the most stunning and powerful devil they had both ever seen, a beauty unlike any they had come across before and her named is Irene.
