I can only remember the ending to this fic, but Sesshoumaru used the well to travel to the future. He met his future self & pups. His future self was sad because Kagome had died during WWII. Past Sesshoumaru decided that he and Kagome were destined for eachother, and tells her so. She gets ticked. Fast forward to the last chapter, it's in the POV of future Sesshoumaru, who tells his past self how to keep Kagome from dying.
>.< That's all I can remember. Please help
(btw, it was on this site)
*EDIT*Never mind, I found it
