After Being Impersonated by the Canary Raised by My Aunt, I Became the Richest Man

I am the grandson of the richest man, but my two little aunts blatantly let the pretty boy they raised together assume my identity, and my mother also favored him. In his previous life, he and his aunt teamed up to kill me. After my rebirth, I no longer allowed them to bully me. I found the richest woman's grandma to support me and expose the pretty boy's ugly face.
