I’ve reincarnated as the reverse harem game’s villainess, the one and only step-daughter of the Eckart duke family.

But the difficulty just has to be the worst!

Everything I do will only lead me to death.

I must be paired with one of the main male characters from the heroine’s harem before the ‘real daughter’ of the duke family appears!

Two older brothers who always pick a fight with me on every little thing.

The insane crown prince whose route will always lead to my death.

‘I only see the heroine and no one else’s wizard, and also her loyal s*ave knight, too!

‘First, let’s take some of them which I see no hope in, out of the list!’

“I didn’t know my place up until now. From now on, I’ll live as quiet as a mouse so you wouldn’t care the slightest bit!

But why do their interests in me keep on rising every time I draw the line?!

[Female strong, 1v1, sweet text, male protagonist paid for the phone bill]

She was the big villain who made the raiders of all planes feel the fear, tearing up all the systems in a fit of rage.

Because it was too boring to be trapped in a small world, Qianyan grabbed a system and started a new mission.

The first plane: The queen worked hard to help the emperor to conquer the country, but was framed and sent to the cold palace and died of illness.

The original owner’s wish is that the children will live in peace, and Qianyan will directly abuse the scum and become the empress!

The second plane: The original owner’s wish is to protect the elder brother and prevent him from being disabled.

Qianyan: Is he not healthy? The original owner, are you satisfied?

The original owner: Satisfied… (really not forced at all)

The third plane…

Qianyan found that there was an acquaintance following her in almost every plane, and she wanted to be with her at every turn.

But she just wants to do tasks and careers, and doesn’t want to fall in love!
