I just finished watching School Days, boy oh boy what an ending, I actually found myself grinning when that bastard got what was coming to him.
Anyways though, I could actually relate to what Saionji was thinking when she committed the 'act' mainly because I've been cheated on by one of my past girlfriends, at one point, I was actually thinking of also committing the 'act' I had actually brought 'the item with which you commit the 'act'' to school that day, but ended up calming down...
