If There Is Still Fate ("Inuyasha" Fan)

I watched "Inuyasha" a long, long time ago. After watching it, the one that impressed me most was Sesshomaru. The story happened to a writer who, for unknown reasons, became Lord Sesshomaru's wife. The journey to the Warring States Period began inexplicably. The story is an intertwining of the Warring States Period and modern times. It tells about some people and their stories I want to express the bond, fate and emotional relationship It's actually an emotional novel disguised as a fan.
