Ok, I think this one was posted on FF.Net, or A single Spark, it's been so long I can't remember... I can't remember the premise, but at one point in the story Sesshoumaru is so obsessed with Kagome that he picks through his harem to find a woman that looks like Kagome...sad to say it, but that is all i remember. I know this is an uber long shot and have kinda resigned myself to a loss, but all the same help would be greatly appreciated!

I vaguely remember reading a scene like that. Right now these are the only two stories I can think of, but I don't think either one of them quite match.

"Temporal Sequence" dokuga.com/spark/story/2856/1
The scene was a memory Sesshoumaru had regained that took place long before he met Kagome, and the demoness resembled a woman he had fallen in love with.

"Yellow Brick Road" www.fanfiction.net/s/4146368/1/Yellow_Brick_Road
He was obsessing over Kagome, but the demoness he picked out did not look like her.

I know I've read other stories where he had a harem, but I can't think of any specific scenes in them that sound similar.

Is there anything else you remember about the story? I'm interested to find out what this fic is, too.
