First, I need to figure out what they're referring to. "Juna juna juice" might be a Japanese phrase. Let me check the translation. Juna could be a name or a term. "Juice" in Japanese is 果汁 (kakushitsu). "Naomisan" is likely ないません, which means "does not make" or "is not made." "Wa" is a topic marker. "Ore no" is "my." "2021" is self-explanatory.
