Transmigrated as the Villain's Doomed Little Sister

Xie Lichu dug too many holes, so the transmigration-into-a-book System sent her into one of the books she'd abandoned, where she became the doomed little sister of a ruthless villain.

Oh wow, exciting! She'd become the beauty who made the hero fly into a rage for her sake.

But beauties die young, and all she wanted was to spend her limited days lazing around, eating, drinking, and enjoying herself.

Then the System told her that if she completed the plot and earned the protagonist's affection, she could live to a hundred!

For a better life, she not only had to work hard to stay alive, but also make sure her powerful villainous big brother lived to a hundred.

She diligently followed the plot, but her brother turned evil, the male lead fell for her, and the female lead confessed her love.

System: Congratulations, you've made it to a hundred!

Xie Lichu: No, wait, just let me die young...
