This is an original fanfic based on the yuri game Towa Tsugai, translated as Eternal Wings. Later on, you'll come across some seemingly inexplicable worldbuilding. Don't be mistaken, it's all from the original.
(I'd be thrilled if reading this made you interested in the original.)
Nightingale is an original character. It's normal if her characterization later doesn't match her earlier portrayal, because I, the person behind the character, fed my own characterization back into her.
My writing skills are limited; I can only write dialogue (looks away).
I couldn't stand the original ending, and my ship got a bad ending again, so I started rambling. And then I kept rambling until this came out ( ).
Chapters 2–6 were padded out to keep the story from moving too fast, so they might feel a little thin. Please bear with me. The main romance plot begins in Chapter 7.
Parentheses in the dialogue are generally internal thoughts, though there may also be some author commentary. Please keep an eye out for the difference (the original manuscript used colors to distinguish them).
Some parts of Chapters 3 and 4 are based on real events.
