At that construction site, people gathered by the yakuza were forced to do hard labor. One day, Suzu, who had no idea about the place, came to deliver from a super cheap bento delivery service that comes once every three days. The workers, who had been experiencing a female heatwave, pinned Suzu down and devoured her. Since then, they have been eroding Suzu's heart and using her as a tool for sexual release every day. In such a situation, the yakuza who manages that place also appears... and the tragedy continues to a shocking pregnancy last.
