I can't remember the name of the fic or who it's by. I've exhausted Google and I still can't find it. I don't remember much but there's two scenes in the story that I remember pretty clearly. One was that at one point Sesshomaru gives Kagome a gift (I want to say he left by the side of the road) that had a poem/note written in English. Another scene in the same story is Kagome serving Sesshomaru tea and I think she was nervous, and his mokomoko wrapped around her ankle? I know that's not much to work with but I want to say it's one of the more popular stories out there. It was the first Sesshomaru/Kagome story I ever read and it's what got me started on this pairing. Any help would be greatly appreciated!

Well the Moko Moko part sounds like it could be
