You were just chilling in the hot spring, while waiting for your swordsman to finish making your sword.

It was a tradition for everyone to be nude at the hot springs,even if they were outside. But you were in the water to your shoulders so no private parts of your body were exposed becouse of the cloudy water.

Your eyes were closed when you herd splashing and opened your eyes just to see Tengen has joined you in the hot springs, standing so the water misty was to his waist.
