Tony and Harley
Either way, Harley loved it. She liked Tony because he was nice to her, and funny, and smart, and easy on the eyes. He was charismatic as all get out.
Harley snapped her teeth at him. "Then I'm your sugar baby." She paused. "Sugar, comma, baby? Or sugarbaby? Sugar glider? Hide in a pouch around your neck?" She leaned on him, putting her head on his collarbone. One hand went out to touch his chest, where the Arc Reactor used to be. "Brand new heart, eh?"
