Nishizono-ke no Kakushigoto | 西園家のかくしゴト

A man who personifies the scum whose sole purpose in life is women, alcohol, and gambling: Hachitaka Kusunoi.

One day, he is dumped by a casual girlfriend he had a somewhat good thing with. Annoyed by her unilateral declaration, Kusunoi heads out alone into the city, determined to fill his stomach.

There, he meets a woman named Sayuki Nishizono.

Upon seeing Sayuki's voluptuous figure, Kusunoi's attitude completely changes. He learns that she lives alone with her daughter, Miyuri Nishizono, and has no husband. He can't help but smile at the conveniently perfect situation.

"This... might be a real find!"

Kusunoi immediately cleverly deceives Sayuki and, without hesitation, installs hidden cameras in her home.

With the malice slowly eroding the Nishizono family, their once happy life gradually becomes twisted and strange.

What remains at the end is a path to ruin devoid of not just ethics but even morality, or perhaps the despair of having sipped from a secret that should never have been known—
