That sounds familiar. I think I know the story, but I don’t remember the name of it and I don’t have it in my favorites. If I’m wrong then I’m wrong, but if I’m right then here are the few details I know of the story I’m thinking of.
I believe Inuyasha goes to future to be with Kagome. Years later in modern time Sesshomaru sees a woman walking with a child with white hair, but the woman’s not Kagome. Turns out Inuyasha left Kagome and is married to another woman. I think he became a movie producer or director or writer. Obviously Sesshomaru and Kagome got together. I think he helped her get over the rejection she was feeling of being seen wanting again after going through it with Kikyou in the past.
Edit: well Fubuki posted the story I was thinking of.
