After I Transmigrated as the Wicked Villainess in a Campus Novel

I transmigrated into the vicious female antagonist of a school romance novel, a girl who was both beautiful and rich.

Because I was the villainess, the System told me to collect the male lead's hatred points.

Only after collecting enough could I leave this world.

To return to reality,

I did everything I could to bully and humiliate him,

and made him my errand boy.

But

Why are his hatred points going down instead of up?!
