Real Heiress, Fake Noble Family

Summary

My mother told me I was the long-lost heiress and dumped me on the Sterling family's doorstep.

But the moment I arrived, my supposed brothers circled around the fake heiress, Lily, like a protective wall.

“Lily is the only sister we’ll ever have. Don’t even think about replacing her!”

My wealthy new parents banished me to a servant's room, warning me not to cause any trouble.

They all assumed I was there to fight Lily for their affection.

So when they discovered I had no biological connection to my new father, they were ready to throw me out, waving a DNA test in my face.
