At a small izakaya, a father and daughter struggled daily to keep their business running. The mother had already passed away, leaving the two of them to manage the shop together. One day, the father collapses from overwork and is diagnosed with a condition requiring three months of hospitalization. The daughter initially considers temporarily closing the restaurant, but is instead forced to take over her father's duties. As a result, she becomes trapped in a situation where, to repay the shop's debts, she must work as a sex slave completely under the control of a perverted man.
