Prompt 757 - Creative

[comicfan]

You thought you had the perfect relationship, but they cheated on you or so you were told. Angry and upset you storm into the woods. After walking for hours you collapse and pound your fist into the ground and hit a rock. You slice your hand and blood drops to the dark soil. A moment later the ground erupts and steam fills the air. A demon stands before you and offers to make a deal partially sealed with your own blood. What deal do you make?
