In author twitter there is an extra about them after the end (Sada is an angel btw). And also another extra about Sada's first love.
Okay, so, this is a very good ending. Mamiya, the cold scientist, ended up falling in love with someone. He wanted to be above everyone, for everyone to see him and his achievement. For him, this was the ultimate goal and a way to honour his aunt (although this was more of an excuse of his selfishness). He wanted to be in a world that would look up to him and him alone. After meeting Sada, everything changed. All his philosophy and ethics were in conflict. He wanted a world where there was just them. A world where they would get accepted. Now, nothing matters for him. It should be a movie.

I love Anne and Nassiens they should both be with Percy tbh. Nassiens already knows how he feels, and it has been showed that Anne does feel like that as well.
They are both very well written (like, there are the skirt jokes and ecchi but at least the female characters have more layers than "being in love", and Nassiens is an unexpected good queer character for this kind of manga)
Such a good fresh story!! It should win an award or smthng
