I am pulling out my hair on this one. I have searched high and low and because I was too dumb to bookmark it a couple years back, I feel SOL.
Okay, fanfic is a Sess/Rin fic.
Seems Rin comes of age and basically she ends up leaving on her own (heartbroken) from Sesshoumaru's domain and journeys to Edo. She stays with Inu and Kag (who are together...reader assumes it is post-Naraku) and ends up leaving, feeling like she is a third wheel... especially since they are basically in the same hut and Inu is frisky.
Then, she journeys and visited with Shippo and his mate in their castle (if I remember, it is Souten... I think), and same issue ensues.
She ends up being accosted by bandits after leaving and Sesshoumaru shows up. He brings her back and they get together. Now, I also know there is a sequel to this as well.
I do remember something like Rin asking Jaken about something Sesshoumaru might think and Jaken says (paraphrasing) "I do not know, my lord keeps his own council."
If you know this, not only will I give you forum karma, but I will be greatly appreciative. Actually, any response will get both...lol.
Thanks!!!
