- Description from novelupdates

Accidentally reborn, Xu Wanwan realized that she was living in a novel and was currently the unlucky cannon fodder, while the fake daughter of a wealthy family was the extremely lucky original female lead!

Her birthright was stolen? 'Sure, take it.'

Her parents were stolen? 'I don't need them anymore.'

Her luck was stolen? 'Well this is the easiest to deal with, I'll just find the luckiest person in the novel and rub some off him!'

Cue Li Jingran, pretty much the embodiment of luck. The closer you got to him, the luckier you became.

There was no way she was going to let such a plug-in slip through her fingers.

As she rubbed off his luck, she regained her good grades, her beauty, her status, and even her horrible parents who were now filled with regret and wanted to reinstate her.

Li Jingran pulled her into his arms domineeringly and said, "Where did this trash come from? Leave my darling alone!"

Xu Wanwan, "I thought I was supposed to be the evil villainess? Why am I so professional at lovey-dovey behavior?"

On the surface, she’s a gay high school boy. In reality, she’s the hacker known as Z, who hunts criminals on the Internet. A girl dressed in men’s clothes; a master at playing games, punishing evil, and having the highest skill in seducing girls. When people learned that “he” was actually female, the entire population blew up!

The previous life is nothing but a joke. Being used completely then abandoned mercilessly. How can I be this stupid to not even notice such an obvious scam? Fortunately, I can have a second chance with my rebirth. Sister, Brother Yi and whoever mistreated me in my previous life, are you ready for my revenge and the counterattack of a princess?
