The tone should be written similar to Fairy Tale was, which is a very casual/laid back third-person limited, swapping around which character to follow as the storyline goes. Obviously as the resident M/C, Erin will be the focus of the show most of the time, but this narrative angle will give me the freedom to follow around Annie/Nik and Jace/Yuki/Minhyuk when I need to (mostly to add comedic flair, but also to push the story in the direction that I want it to go?).
Also, here's the list of families since I don't think I've written them anywhere?
Erin - only child, has both parents
Annie - oldest of 4 (brother - Cian!!, younger twin sisters), lives with parents & grandparents
Nik - has both parents, and a much older sister who moved out and now studies in England or something
Jace - has younger brother & dad, mom died of cancer some years ago, but dad has a new gf that his brother hates
Yuki - has both parents (but she's adopted so they're very old and white)
Minhyuk - lives with mother and younger brother, older brother and dad reside somewhere in Korea
