The Blackmail 1 Episode 1

Aya thought Yumiko was her best friend, but things took a dark turn when Aya developed feelings for the same boy Yumiko was interested in. In a twisted act of revenge, Yumiko circulated compromising photos of Aya, turning her life upside down and forcing her into a degrading situation. But Yumiko's thirst for vengeance didn't stop there—she dragged Aya's friends and even her family into the nightmare. Together with her male friends, Yumiko blackmailed the girls into the most depraved and humiliating scenarios imaginable. With friends like Yumiko, Aya certainly didn't need any enemies.
