After Gaining the Ability to Kill, I Became a Female Hooligan

[One heroine with multiple love interests + sexually experienced heroine + deranged yandere + wealthy families + satisfying revenge + revenge story + invincible heroine]

The heroine had an unhappy childhood. Her younger brother was kidnapped, tearing her family apart. After her parents divorced, neither wanted her. She was bullied at school, ostracized at work, and her life was a complete mess…

After unexpectedly gaining a god’s protection and becoming all-powerful, she decides to take revenge.

(P.S. I was going to end the blurb here, but Ning Tusi read it and wasn’t satisfied. She said: “With powers that strong, she can’t just focus on revenge. Flirting with men has to be part of it, too.”)
