The Devil In Her Dreams

There was one thing Adele was running away from and that was death. Little did she know that she was going to dance with the angel of death. Or rather, the devil himself.

"What are you thinking, little one?" He was towering over her while she raised her head to look at him. His gloved hands were situated in his pockets as he stared down at her.
"Will you do it or not?" He was serious. His eyes held no mockery or sarcasm.
Adele had already made her decision. But she knew she would surely regret it in the end.
"Yes... I will do it." She muttered. Her shoulders fell as those words left her mouth. There was nothing she could brag about again.
"I didn't hear you. Maybe you should tone up a bit."
She shut her eyes in irritation, still with her white knuckles.
"I said I will do it." She swallowed to urge to haul any abusive word at him.
Before he could say anything, she picked up the contract and walked past him to the desk in front of them. She took a pen and signed on every required slot.
Mr. Hale wondered about the kind of woman he had landed this time. She was feisty and strange. Somehow, he couldn't read her at all. His eyes never left her, even after she signed the contract. Adele wanted to hear him tell her to leave and come back the next day. Everything was already so tiring for her and she needed rest. Plus she needed to take her drugs before she became a bloody mess.
"Strip."

Adele just wanted to extend her lifespan so that she could bury her grandmother. But due to lack of resources, she couldn't foot her bills and ended up in the hands of the devil who promised to take away her illness.

What happens when he breaks his promise and she dies? There was only one thing on her mind before she started from the world of the living; revenge.
