The Real Heiress vs. The Boss Bitch

Summary

The sister who was switched at birth came back.

My idiot college-student brother instantly turned into the fake heir.

He hugged my leg, sobbing like a baby.

"Sis, my one and only sis, how will I live without you?"

Annoyed to death, I kicked him in the chest. "Act normal."

Just then, my new sister walked in and saw everything.

She stormed over, furious and indignant.

"How dare you bully him?!"

Me: "???"

Later I found out, she thought I was the one switched at birth.
