Hi! 😊 From what I understand, it's mainly a promotional wording thing. Even though only one song has been officially released so far, that song is part of his EP. So when media outlets say "his new EP" because they're promoting the entire project rather than just the currently released track~ think of it like when an artist releases the first single from an upcoming album, they'll often say "from the upcoming album" even though the full album isn't out yet.

I could be wrong if his team changes the release plan, but that's how these promotions are usually done 🩷💚
