The reason why Yatou is called Yatou is because he calls her that.
The girl called him Master.
Originally this was quite boring, a child's nickname game - but the girl just liked it.
This reminds me of leehom's lyrics.
"Let me love you very deeply, very far and very classically."
Yatou's story was once updated very slowly on a BBS.
Because it is completely in sync with the girl's life.
It is not even known whether there will be a final chapter.
But it finally came to an end.
Maybe it's just that sentence,
"We were young. We were wrong."
