He snorted faintly at the comment about the elephant and model building, leaving it to Kaoru to decide. He had already made it clear that the red-head was in charge of decorating the house, so long as it wasn't too cluttered or garish, and Seimei's own room was left untouched. Minimalism was conducive to a clear mind.

When the boy's head settled on his shoulder, he leaned and rested his head atop Kaoru's, eyes remaining closed as he sat there, just content to share the space and moment. He was unconvinced it was enough, but when one wanted to give another the world and only had so much to work with, they were unlikely to ever be certain about what they did. So he made a soft sound of understanding, if not agreement, and rested a hand over Kaoru's, comfortable in that moment.
