I think we all should know that if her Arena Tour was named after the latest CDL, then it's going to be like this, the setlist will be quite similar. Then, about the lack of A ONE songs, it's kind of normal I think because she didn't name her tour with an album name or something, but this is just first show, more songs will be added later I think.
Most of A ONE songs will be placed during the encore imo.
Other than that, I love the setlist! The last four songs in the main show is awesome
