Transmigrated as a Wicked Woman, Serving as a Dog for a Rich Heiress

[Yuri]

Jiang Wuxia was born into this world already as a vicious supporting character and the adopted daughter of the nanny, the small loyal dog who followed the wealthy family's young lady around, kept by her side like a pet.

For twenty-four hours a day she was summoned and used at close range, working tirelessly and coming at a call.

But the system wanted her to betray the wealthy family's young lady Si Tingxue, the villain, and raise Si Tingxue's blackening value to 100%!

It wanted Si Tingxue to become her slave, her eyes ruined, and die without a burial place.

Looking up at Si Tingxue's back, Jiang Wuxia had long since let her feelings turn crooked.

Let the protagonist kill the older sister? Let her let the older sister die?

Impossible! The older sister can only belong to her!

How dare this bunch of ants cross the line!

She would always be the older sister's most loyal subordinate. If the older sister told her to do anything, she would do it. She wanted to forever crawl at the older sister's side.

Si Tingxue awakened.

She saw that Jiang Wuxia, the one she had raised by her side since childhood, would one day kill her master, betray her, humiliate her, and run off with someone else.

Absurd. She would not allow her "pet" to do such ridiculous, insubordinate things.

If her loyal dog would not behave, then she would need to be punished twice as hard.

Isn't that right?

Both sides have flaws in their personalities; neither is a typical good person.

The worldbuilding is original. Do not project reality onto it.
