Miku always remembered a limerick someone wrote about her -- "I don't listen to what's going on outside the window, I just want to dance, I can't afford to be hurt. The person who wrote the poem told her, "Square dancing is not ballet, and you can't possibly go up to the big time."

"This is the day I raise my eyebrows," said Mijou, looking at the blue dome of the Water Cube, thinking that square dancing's time has come.
