Kakashi was half on his way to dosing himself when Yamato spoke, and the sound surprised him awake with a soft mumble that he managed to disguise as a noise of thought. Was he really going to end up falling asleep in Tenzou's bed? He hadn't slept beside or even close to the man for five years, and now they were going to wake up tangled together. Typical.

The thought made Kakashi chuckle a little, and then he realised he had a decision to confirm.

"Yamato.." Kakashi mused, testing the name out on his tongue. It was a good name. Strong but simple.. He supposed it suited Tenzou well, although...

"I'll never be able to remember that.." he muttered, smoothing his hand through Ten- Yamato's hair softly, the closest to 'I like it' as Kakashi was willing to get.
