idk if I'm right or wrong but this is based on what I understand about asada meant by gold and youth so on. So in chap 3, when the first time Asada met Himari and he said "he sparkles brightly" which means like a gold. On the other hands, in the last chap Himari mention why the "youth" character written "blue" in Japanese character (which means the word can be read as blue or youth in a sentence) like it can be red or yellow but to Asada the "youth" to him should be gold because that's how he sees Himari ;)
note: sorry if you still don't understand about this, I try my best to explain but I also still confused myself^_^
that made perfect sense!! thank you so much for explaining!! that’s so cute!
i loved this story so much, but can anyone explain the gold/youth thing to me?
