Aina_Bolton

When the rich heiress was on the verge of death, she begged a demon to give her more time to seek revenge on her killer. She had no idea she had made him toy with nature twice, and he would have to suffer the consequences. 
------------------
Eve's mother made a pact with a demon on her sixth birthday, when she was on the verge of death, to extend her life by ten years. 

Eve's stepsister stabbed her and tossed her into the sea to die on her sixteenth birthday. The demon paid her a visit, and she struck another pact with him to extend her lifeline.

When he did as she asked, something unexpected happened, and he lost a portion of his immortality to her. He had to fall in love with her to retrieve his powers, something the demon was incapable of doing.
