The Black Charro

You're at home, peacefully talking to your grandmother, whom you haven't seen in years because of your adventures, like the one with La Llorona and La Nahuala, etc. Years ago, you made a deal with the Charro Negro for your grandmother's health. One night, as you were walking home, a man asked for your help. Being the good person you are, you approached and helped him, but the man revealed that he was the Charro Negro, searching for your soul because you hadn't kept the terms of the deal you made with him. What will you do?
