The tree knows of his suffering.
He feels the soft caress on his face. Cold little strands demarks his face, a petal smoothers the path, adding a new feeling in this experience: scent. He is against a tree, with his head laded to the side and the light makes patterns on his face while the wind moves the foliage of the tree.
But he doesn't feel the nature in the caress.
He feels the energetic Hokuto, with his shinny presence and cold hands, waking him. He feels the smooth touch of Seishirou-san and the smell of Sakura the man always carries.
Subaru slowly opens his eyes and sees the lulaby the tree makes to him. "Thank you". Maybe he's not alone in this crossed path between both clans; at least he has the tree. And the tree has Hokuto and Seishirou.
That's enough to him.
