Grief
Inutaisho has done a horrible thing, he knows.
Horrible, at least, in the eyes of his son, and in the eyes of many of his men.
He has taken a human wife.
They do not understand the appeal. There are moments he doesn't, either.
But Izayoi is sweet, and gentle, and generous, and completely unlike Yukishima. He loves her, and, for a moment, perhaps, she can dull the ache in his heart, the one that hasn't left him since he found his wife in the snow, his son clutching her hand and screaming.
It is something he will never forget.
Sesshomaru seems to think that Izayoi is there to somehow usurp Yukishima's memory. How, he often wonders, could his son think that, when not a day goes by when she is not on his mind?
Izayoi is in his heart, yes, and she always will be. He loves her, but there is no love in the world that could make him forget his first wife.
She gave him his son.
And there are moments, though he thinks less of himself for them, when he lay next to his human wife, listening to her deep, even breathing as she sleeps, and he misses her. Even while Izayoi sleeps peacefully in his arms, he misses his first wife, the demon who held his heart, and he grieves.
Not just for the loss of a wife, but for the loss of his son, who will never forgive him.
End
A/N – Again, I'm depressing. But hasn't this occurred to anyone else? (crickets chirp) …Er, right.
