I read this story awhile back, Sesshomaru is in Kagome's time and I think they're trying to find a way to send him back?? Anyway, there are a couple of scenes I remember,

1.) Kagome's dad goes to sesshomaru's house looking for her, I think he (Kagome's dad) was trying to take her and give her to a gang he owed.

2.) Kagome and sesshomaru discover the fights and Kagome meets up with koga, he takes her to a roof top where they make out a little. Sesshomaru is really angry and tells her koga's wolves killed Rin.

Any help would be appreciated
