The Villain’s Younger Sister Novel

Nie AnAn awakens to discover she has transmigrated as the villain's adoptive younger sister. In the original novel, he conquered ruthlessly while she perpetually cleaned up after him—together embodying the story's darkest forces. Her arrival shatters this predetermined doom the instant her delicate nature causes her to faint witnessing bloodshed.

What unfolds proves entirely unexpected:

Her rivals suddenly perceive her vulnerability as something demanding fierce protection; the original male lead grows frustrated watching his once-devoted admirer grant him no attention whatsoever; Young Master Nie treasures finally having the beloved sister his parents bestowed; and the cold, merciless villain returns home progressively earlier, his harsh words softening into quiet affection.

Villain Brother: AnAn, come over. Let me try some of it.
Nie AnAn: Hold on, gege. It's not ready yet.
