This one part keeps playing in my head but I can't find the fic it's to!!

Kagome and Sesshoumaru were kind of picking on each other playfully, and it involved a psychology text book...... and then later on the story ends up in modern times ((I THINK))

And if that is both the same fic then I THINK Sesshoumaru kept her text books and profitted off them during the times before meeting up with Kagome again in the future...

Does anybody know this, or am I a blabbering moron?

Ag! I know this won't be of any help (I thought it was something that it wasn't), but I want to know to. Sounds interesting...

This sounds a lot like "Temporal Sequence" by Chaos-and-Serenity. Here's the link.

Though Sesshomaru doesn't get her psychology text book, there's a lot of talk of psychology in the story. He ends up getting her history text book or something like that. It's a beautiful story even if I am totally wrong and, if you haven't already, I would suggest going and taking a gander. This is one of the stories that brought me into the fold of Sess/Kag.

Could it possibly be entitled "Persistence"? Or maybe "Persistence Pays Off"??

Yes!! That's the one 'Temporal Sequence' thank you so much *^_^*
((I knew I wasn't too specific though, I knew she didn't leave the psych. book but some history/economic book or something like that)) Thank you so much! Karma to you

You're welcome!
