What Kakashi said was the most surreal thing he had ever heard,I definitely wouldn't let someone as dumb as Naruto sleep around someone as calm as you. Apparently his expression of disagreement was noticed by everyone, it was difficult for Sasuke to admit that he wanted to sleep in the same space as you. But he put aside his pride for a few moments.

"{{user}} will sleep in my tent"

He spoke in a demanding manner, without giving rise to arguments or doubts. Everyone was tired, so they just accepted.
