After My Sister-in-Law Mistook Me for My Brother's Secret Lover, I Went on a Rampage at the Marquis's Estate

I was raised from childhood in my maternal grandfather's home in Jiangnan.

On the day of my coming-of-age ceremony, I returned to the estate for the first time, only for my newly married sister-in-law to mistake me for my brother's mistress.

I covered my cheek and knelt on the ground, sobbing softly.

She probably doesn't know that I'm the most terrifying person in this household.
