Sesshoumaru revives Rin, Rin follows Sesshomaru. Then she stays and he lets her. But why? And after that? Attempting to explain the odd relationship between the two.
I got the idea from the Fukai Mori ending theme, as Sesshoumaru visits his fathers tomb. As he decides to go there once more, Rin, as usual, follows along. She ends up learning a bit more about her caretaker, and he learns a little more about himself.
Rin reminisces about the day she met her Sesshoumaru-Sama and what she's always thought of him. We get to see into Sesshoumaru's "feelings" about little Rin and some thoughts on why he allowed her to follow him that fated day.
