My sister was contacted by the company where she works from consumer finance and decided to quit her job. The cause was a large debt made by the younger brother who lived with him ... Even so, in order to repay the debt that her younger brother had, her sister works like a robot at a convenience store. - Her spirit gradually wears out from debt and fatigue that does not decrease, and when everything becomes irrelevant, her sister has become a convenience store woman who is convenient for a man who has sex with anyone anywhere.
