Sango was new to this world, but she had magic here, and had enrolled at Hogwarts. It took her awhile to get used to Kagome's world, but she managed it.
Sango hadn't expected anyone to ask her to the ball. She mostly kept to herself. When Harry got her a date, of course she said yes. She didn't want to go alone.
Besides she was never going back to the monk. Sango had to move on.
But when she met Ron, she had to say, she really liked him. He was cute and shy and a surprisingly good dancer.
"Thanks for showing me such a good time." Ron said. "I thought this dance was going to be horrible, but you made it brilliant, Sango."
"How bout a little more brilliant." Sango smiled, and kissed him good night.
Ron stood there watching after her as she left, a dreamy smile on his face. Sango smiled. This was a start of a good thing.
Sango didn't notice Hermione making her way to Ron, looking furious.
