Spoiler (highlight to view)
I probably wasn't the only one who really felt how sad it was when Sai actually disappeared.
It doesn't have to be a tragedy, but if it is, please no gruesome/disturbing manga. Some blood and gore is fine, but there's a point to which one starts to wonder if there really is a point to it all. I get it, s/he's bleeding, move on.
And if it's a shojo, I want to be able to tell the difference between the guys and the girls; i.e. there should at least be some hint of testosterone in the male characters.
