- Description from novelupdates

This is a cliché story about two young people saving the world.

I, Lu Li. had an agreement with the system; once the plot was completed, I could go home, but the system played me dirty.

Demanding another round, claiming the plot had gone awry.

Let’s perish together, scumbag system.

You’ll never see me endure such humiliation again.

Sadly, I didn’t die.

Filled with rage, since you won’t let me die, then I’ll make those who once shamed me, hurt me, and betrayed me in haste, pay the price.

The protagonist is not humble, not clinging…

The happiest thing in the world is to be able to amend what you have done wrong. She who acted willfully because of a game, was reincarnated into a time when she still had her parents’ love.
