Edward couldn't help notice a bit of a change in Winry. Nothing like a personality shift or anything, just her physical mannerisms. He indulged the behavior. When she handed him something, whatever it was, she touched his hand and didn't let go. They both took note and made eye contact. Winry blushed, "What is this feeling?" she referred to the feeling in her chest.
"Magnetism," he said pragmatically and pulled her fingers to his lips and kissed them lightly.
Her face went red, "What was that feeling then?"
He smirked, "That's electricity."
