Words can't begin to describe how... better, it is than the actual latter half of World Tour. Everyone, no matter how badly they've seemed within the actual show, is redeemed. Everyone.
But this story doesn't just focus on Courtney/Cody. No, we've also been given some hilarious moments, mostly with Owen and Noah (a good example being at the end of the song in the Niagra Brawls chapter, and a non-Owen and Noah example would be the in universe results for the best pairing), some intense backstabby moments, and a rather heartwarming feel throughout the entire thing.
Honestly, the characters are written so perfectly, I'd rather have this be my headcanon of the latter half of World Tour. It's just so much better.
