After Rebirth, Beat the Fake Green Tea Daughter

In my previous life, I didn't understand the twists and turns in a wealthy family, and I couldn't see the slow calculations of the green tea sister, who finally died in a sea of ​​fire. After being reborn and returning to the Su family, I am determined to make her pay the price. I don't want a biased mother or a blind fiancé. I just want to protect him well and rush in to harm him regardless of danger for me.
