A hot spring hidden deep within the Mist Village.

This hot spring is the only sanctuary Kakashi visits every night.

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

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 wouldn't normally be able to say.
