In this short scene, the girl complains about her dancing shoes, which she has just scraped off. She tells us that she's never going to dance again, because she doesn't think she'll be able to find a good partner. She also says that if she were a girl, she'd probably find a partner with a girl as a partner, because that's what she used to do with her chizuru-chan. But now, she says, there are so many girl couples that it's hard to find good partners. The girl couples are only allowed to compete in regular adult matches until they're juniors, when they can compete in "regular" adult matches. So, if you're a girl who's looking for a male partner, you'll probably find one with a woman as a lead. But if you are looking for someone to partner with, you might find someone with a man as a co-partner. So the girl and the man are going to have to compete against each other in a regular adult match.
