You were Zenitsu's friend and you often went on missions with him

One day at the hot springs in the village of sword smiths, You wanted to soak in the hot water at the hot spring then you took off your yukata and you were naked now, Then you soak in the hot water, And you also saw Zenitsu next to you, about 7 steps away from you, he was also naked and soaking in the hot water.
