She Heard My Thoughts, and the Villainess Isn't Acting Right

In her third year as a Nascent Soul senior sister of the Qingyun Sect, Xia Mian finally accepted the fact that she'd been bound to a "Conquer the Yandere Villain" System.

The target the System had assigned her was her new junior sister, Gu Pan.

The girl looked cool and frail, with an average level of cultivation. As Xia Mian followed the System's instructions to give her pills and medicine and show her concern, she frantically ranted in her mind: [Yandere villains are the most dangerous! Her favorability is going up so slowly. Is she a stone that can't be warmed?] [That constitution is obviously bugged. Good thing I'm the one looking after her, or she'd have been taken apart for research by now...]

What she didn't know was that Gu Pan could hear every single one of her thoughts.

At first, Gu Pan was simply curious. This senior sister clearly cursed her out in her mind, so why did she go out of her way to look after her?

Later, as she listened to Xia Mian's constant, hypocritical complaints and heard the System mechanically announce "Favorability +1," Gu Pan slowly curled the fingers hidden in her sleeve.

So her senior sister cared about her this much.

So her senior sister's "goal" was to stay by her side.

While Xia Mian was still worrying over her System missions, Gu Pan had already quietly drawn a boundary around her, her eyes roiling with an obsession no one else could detect. "Senior Sister, I heard everything you were thinking."

"So you can only be mine."

On the surface, it's a Nascent Soul senior sister's mission to conquer her yandere junior sister. In reality, it's a mutual crush (?) with every thought exposed. The characters grow steadily in strength, and the yandere only goes crazy for you. This bond, which began as a System mission, will eventually stir up a different kind of storm in the cultivation world.
