Specific Search-Sess/Inu; Marriage Proposal

[midnight12reade]

I have been driving myself crazy trying to hunt this fic down and thought I would try and turn to the experts. Does anyone recall the fic where Sesshoumaru sends some type of marriage proposal/contract to Inuyasha and Inuyasha knows what it is immediately from the color of the cord/string it is tied with? Sesshoumaru and Inuyasha end up exchanging silk or cloth with embroidery that shows their intent or regard for each other. The rosary around Inuyasha's neck blocks Inuyasha's senses of the land. Kagome is threatened/guilted into removing it and Inuyasha once again feels the connection to the land/territory. I believe their is some type of prophecy. I believe that in this story (could be another I am confusing with it)-they travel to some type of shrine or monastery and there is a mating hunt where one is supposed to hunt down the other as part of the ritual/mating. I remember in this fic that Inuyasha reacts more like a Prince and follows/knows more demon protocols.

Any help anyone could offer would be greatly appreciated. Thank you!
