[Synopsis]

Natsumi is a housewife who has become addicted to pachinko.
She even dips into her children's school savings behind her husband's back.
After being rejected by many consumer loan companies and at a loss, she meets a man who works in the finance industry.
The man says he will lend her money but asks for obscene photos of Natsumi as collateral.
Natsumi has no choice but to do as the man demands and takes obscene photos of her.
However, just as the man expected, Natsumi's destination is the pachinko parlor.
In the end, Natsumi spends all the money she borrowed and kneels naked in apology.
The man's next request is for a "live broadcast."
