Her parents, adoptive father, and master all died at the hands of the same person. Even her lover died because of it. She said that she survived only for revenge.
He hated killing and longed for freedom, but in the end he plunged into the bloody rivers and lakes without hesitation, just for a promise to her - he said, you live well, and I will seek justice for you.
He accompanied her through the ups and downs, retraveling the memories of her and her old love; he looked at her, his eyebrows lowered, unable to hide his endless longing for the deceased... Until the wedding dress was wrapped around them, and the fiery red light reflected each other's eyes...
Purpose: If the sword is ruthless, where will justice be?
