Please help me find this story I'm losing my mind over it. It's and older one and Kagome has aspergers or some type of autism in it, she's great with numbers and uses her ability to help save a kidnapped Rin. Inuyasha is marrying Kikyo and slaps Kagome while wearing a huge engagement ring. She and Sesshomaru help plan the wedding. I know that's vague, but I have been looking for it forever. Any help would be amazing.
Sincerely,
Shattered
