Kakashi's hand found purchase in Yamato's hair, his palm and fingertips pressing through brown locks to massage in small circles at the younger man's scalp. He was surprised to find himself relaxing as he felt Yamato settle at his side, comforted by the willingness of the younger man, by the lack of reluctance even in when posed with showing weakness.

Kakashi held him through the shakes, his hand massaging and his arm tight and comforting, grounding, defiant in keeping Yamato secure and safe.

A little while passed, and the only movement Kakashi made was to turn the page, and to eventually rest his head on top of Yamato's as he read about the structure of buildings in the previous century.
