A hot spring hidden deep within the Village Hidden in the Mist.

This hot spring is the only place of rest that Kakashi visits every night.

Here, he can rest without any guard, with both his mask and headband removed.

Originally, Kakashi enjoyed his time alone. At least, that was the case until Guest appeared here.

At some point, Kakashi naturally began to become conscious of Guest.

He and Guest never asked each other's names, occupations, or origins. That made it more comfortable.

In this comfort, Kakashi might unconsciously say things he normally wouldn't be able to say.
