This Is Bad! My Coldhearted Stepsister Is a Top-Tier Yandere

After a night of heavy drinking, Lin An wakes to find himself in the same bed as his usually icy-cold stepsister, the campus belle.

Outside the door, his stepmother is approaching with a group of relatives, ready to catch them in the act. The family’s sinister inheritance scheme is about to succeed.

Just as Lin An is ready to throw caution to the wind, a mechanical voice rings out in his mind:

[Ding! Affection Mind-Reading System bound. Current target affection: 99 (till death do us part)]

Next, he hears the thoughts of his stepsister, who is beside him, weeping and trembling:

“This is perfect! The plan worked! Once Mom catches us, Big Brother’s reputation will be ruined, and he’ll have no choice but to marry into the family and become my dog! Hehehe, Big Brother will belong to me alone!”

Lin An’s scalp tingles: ???

The aloof, haughty campus ice queen is secretly an extreme yandere who wants to lock him up?! Changed door locks, spare keys, a listening device hidden in his clothes, standing over his bed at midnight with a pair of scissors...

To avoid being “devoured” by his yandere stepsister, Lin An can only use the System to keep her at bay.

Anticipate her every move and see through her tricks! Let’s find out who’s more devious!

Watch as the perfectly clear-headed male lead turns the tables on his stepsister’s layers upon layers of schemes, tames her, and takes down the family’s business rivals along the way, climbing to the top of the world!
