Atsushi was living at his brother's house while looking for a new job. One day, he consulted Kasumi after a nearby man picked a fight with him over his girlfriend. However, Kasumi, facing the unreasonably angry man, was threatened using her brother-in-law's life as leverage and ended up accepting the man's lewd demands... unaware that it was all planned... After hearing about his sister-in-law's humiliation from the man who toyed with Kasumi, Atsushi directed a mix of jealousy and lust towards Kasumi, who had sacrificed herself for him.
