Make sure you don't use scrapped drafts and incomplete design drafts that are sent after the main text.
(If I write a series, I might pick it up and use it)
(But the series is too tiring and I probably won't write it anymore)
(So just think of it as a side story)
(Seeing it is fate)
In addition, there are various texts that will not be published in the main text but can be used as reference materials that I find interesting.
Thoughts: Deleting it would be a waste
