- Ear Worm: "Sasurai nagara, kizutsuki nagara... Ashita no taiyou sagashite iru no...."
- Germans Love David Hasselhoff: The series was an absolute HIT in Italy (as Jane and Micci) and France (Nathalie et ses amis). It's speculated that the Italians embraced the series so much because early Italian music industry had MANY performers who, like Nozomi, were dirt poor as youngsters and built their careers from next to nothing.
- By contrast, the show had low ratings during its initial broadcast run in Japan, which did not reverse the declining fortunes of Mushi Productions (which would declare bankruptcy not long afterward) and may also have been why Nozomi's seiyuu Junko Fujiyama voluntarily dropped out of the public eye very soon afterward and refused to resume her professional career. The anime would later gain popularity in reruns, which led to some demand for Fujiyama to sing professionally again; however, she wouldn't release another recording until 2008, and apparently returned to being a recluse afterward.
- Some Anvils Need to Be Dropped: Yes, rich people can be snooty. Yes, poor people can be kind. But that does NOT automatically happen because of their birth: what makes the trick is the person's environment. i.e, Nozomi is a sweetheart and Miki's a snot, but their moms are huge influences in them. Plus Michiko is NOT swimming in riches, but she's a huge asshole and not even her Dark and Troubled Past justifies her revenge..
- There's also quite the criticism to the capitalistic post-WWII Japanese society and its cut-throat entertainement industry. Which turned out to be... prophetic.
- The Woobie: Nozomi is tailored for this trope, what with her very harsh life that technically shouldn't have been hers to begin with.
