Math
Athrun's teaching Cagalli arithmetic
He said it was his mission,
He kissed her once, he kissed her twice and said,
"Now that's addiction."
And as he added smack by smack
In silent satisfaction,
Cagalli sweetly gave the kisses back and said,
"Now that's subtraction."
Then he kissed her, she kissed him,
Without an explanation,
And both together smiled and said,
"That's multiplication."
Then Kira appeared upon the scene and
Made a quick decision.
He kicked Athrun out with his Freedom
And said, "That's long division!"
