Hey, i just finished a new SessXKag Fanfic that is MUCH better then 'Their Differences' Plus it's hilarious! Here is the link, i highly recommend it :3

It is called "All That Is Mine" and the summery is this:
Sesshoumaru needs a new secretary but doesn’t want one…until his father introduces him to her…a very feisty human by the name of Kagome. What better way to start off their relationship then to find Kagome insulting his half brother, Inu Yasha?
