The Blackmail 1 Ep 1

Aya thought Yumiko was her closest friend, until their rivalry over a crush turned toxic. When Yumiko obtains scandalous photos of Aya, she uses them to strip away innocence, reducing her to a desperate toy for pleasure. But cruelty deepens—Yumiko drags Aya’s friends and family into twisted games, forcing degrading acts through blackmail. Betrayal burns as Aya endures relentless humiliation, helpless against Yumiko’s hunger for revenge—proving friendship can mask the darkest enemies.
