The villainous Family Is against Independence

I became an illegitimate child of a bloody villainous family with no family love; Elodie, who had a weak body and a nervous attitude, also bullied the servants.

´Three years from now, my sister will be adopted. ´

The female lead, who was adopted as a political tool, will melt not only our father but also the whole family with her loveliness.

"Let’s earn some money and become independent from this family by the time my sister shows up!"
… Or so I thought.

“Independence? What kind of bullshit is that?”

“Who put such thoughts in your head?”

“Sister, you’re certainly not going to run away from home, right?”

Why was my family against independence?
