The silly sweet half-fairy pretending to be a robot fell in love with the sultry little fresh meat.

He was tolerant to her because he was afraid of spending money on repairs. He was inexplicably doting on her because she was the only one who could talk among the electrical appliances at home... The half-immortal puffed up his face, it seemed that it was time to let him know the difference between himself and other electrical appliances.
