Mercy's Angel

I wanted her, yet she pushed me. Now she's at my Mercy.
Angel
Seeing my happiness surrounding me. I want something for myself. Only the one I want has all but disappeared. My brother told me she was leaving town. I figure she was running. Then I found out the truth, and now she's stuck. I'm not letting her getaway. Not when she's got something of mine. She can fight me all she wants, but I'm not gonna lose her. I'll keep her at my mercy, but in the end, I'll be at hers.
