Well I'll definitely think about either adding in more plot or changing the ending. If I do end up writing more I'll include important characters like Okiya and Eri.
No promises though, I'm getting pretty shit marks in school at the moment and I need to apply to university so i can go next year so I have to bring my grades up.
If you guys having any suggestions or want me to include something inside the story just add a comment here and I'll try to put it in.
I actually had an alternate ending to the whole story I might switch it up because it seems that no one wants Kogoro to die (I don't either but hes can be pretty stupid sometimes and with Shinichi back it'll put him out of business lol)...I'll think of something =P
