She gave everything to help Third Prince Helian Heng ascend the throne, only to be discarded once she was no longer useful. On the very day he achieved his goal, he personally handed her over to another man in exchange for the command tally to three hundred thousand troops.
After using her to the fullest, he cruelly had her killed. If you don't love someone, at least don't hurt them. Helian Heng, who used someone to the very end in the name of love, was the scum of all scum!
Tortured to death, she swore to take revenge at any cost, and sold her soul in exchange for a chance to do so.
Agent 5354 took on her revenge mission, sending her back to life eight years earlier. Her stepmother tried to control her, only to be controlled instead. Her scheming, innocent-act sister tried to bully her, but no way was that happening. Even the scumbag Third Prince wanted to use her to rise to power. Let's see how she runs circles around him.
Reborn, she swore to punish every scumbag she met and live life on her own terms!
But she accidentally got involved with the man she'd had a one-night stand with in her previous life. From then on, a young lord joined her on her path to punishing scumbags: he applauded as she took them down, and handed her the knife when he killed!
"My lady, tired of punishing scumbags? How about we try a different kind of fun, like having a few little monkeys to play with?"
