Jasmine goes to the devil mafia boss for help, will he help her? And what will he ask for in return?

Axel is the devil and he's been the king of hell for as long as anyone could remember. He is cold-hearted and ruthless but does not hesitate to kill anyone who harms a woman or child. So what happens when Jasmine comes running to him for help after her mother is killed right in front of her? What happens when Jasmine signs a deal with the devil who is simply looking for a psychologist/companion? What is she really ready to give in return?

Axel is cold and heartless but aside from having a soft spot for women and kids, Jasmine seemed to have come into his life and broken down his walls. Will he let her? Or will she run away when she realizes how messy loving the devil can actually be?
