@Shiawase_Rina

thank you for information, this story really make me wonder why it stop at half way for many years >-<"

so mangaka choose to end with other characters chase to this case with no answer come out yet to convey how original work still not solve it

well, I think it's best choice mangaka could do with respect to original story by not interfere with it

Thank you guys for scanlating the manga even with the project being abandoned (which is why the manga has it's own ending because the novels just stopped).
For everyone else who didn't know what happened. The author of the series Suzumu uploaded songs that were not made by him under his name and made money off these songs.
In 2015 he admitted what he did and said that he would stop all his Vocaloid related projects (Meaning Shuuen no Shiori as well).
Words cannot describe how frustrated I am about this situation. I think we can say that we will most likely never know the truth of the story.

Can someone tell me what the hell happened?

Wait. No. This can't be the ending. Wtf

I really don't understand the ending :/
