This is the first time Shouko change her hair style to ponytail. What's the reason ?
I get the impression that you'll get the context of it if you read the rest of the chapter. One thing to note: tsuki ga kirei, or "The moon is beautiful", was an old way of confessing.– MakotoSep 20, 2017 at 2:35
did you mean this one ?– GagantousSep 20, 2017 at 2:55
No... The saying is from the 1800s, or rather a very long time ago, when Japanese people couldn't really express "love" as we in the modem era understand it.– MakotoSep 20, 2017 at 3:30
If you scroll down to the "other uses" of the phrase in that article, you'll see why it's considered a confession of love.– ConManSep 20, 2017 at 23:57
I find the answer in Volume 4, chapter 24 ( read from right to left or look at the page number )
Volume 4, chapter 24, page 6,7,8
Ishida realized that what Kawaii do to her appearance is clearly the same with Shouko at chapter 23. It's pretty obvious that Kawaii like Mashiba.
So The reason why Kawaii change her appearance is because she want to look attractive in front of Mashiba. It's same with Shouko case.
It's just my speculation but from the interpreter of the story at chapter 23 said that Shouko want to look attractive ( she want to looks different ) in front of Ishida, and after that he confession to Ishida but it didn't go so well. But Ishida still didn't know what shouko feel toward him.
3You should explain it with the text. Text is the main tool for the explanation, while images (and external links) are considered as a supporting tool. The reason is, text is indexable/searchable, while image is not. Your answer should stand alone as if there's no image/link.– Aki Tanaka ♦Sep 21, 2017 at 16:04
