Fusa plot
Long ago, plans were made for Seishiro to marry the daughter of the chief of the palace guard, but his social status remains too low. The Iwai family adopts him to give him the status necessary to marry such an exalted person and nothing seems to stand in the way of marriage anymore. Then a beautiful woman arrives at the castle, who can only remember her name, Fusa. Seishiro instantly falls in love with her and marries Fusa. Only now he has to live with the fear that she will one day regain her memory and then be forced to leave him.
