Prologue
One day, my old, frail body suddenly rejuvenated into that of a vigorous youth in his twenties.
"Is there nothing you wish from this master? All the things I couldn't do for you in my old age... I want to make them up to you now."
They were my precious disciples, whom I'd cherished like daughters. All I wanted was to help them with a father's full devotion...
"Master, then... could you tell me one thing?"
"Haha, speak your mind, whatever it is."
"The way to become... your loving master's wife♡"
"......Eh?"
Something had gone terribly, terribly wrong.
