After Being Recognized by My Sister-In-Law as My Brother's Concubine, I Went Crazy in the Hou Mansion.

I was fostered in my grandfather's home in Jiangnan since I was a child. On the day I got my haircut, I returned home for the first time, but my sister-in-law, who had just moved in, recognized me as my brother's wife. I kneeled down on the ground and sobbed softly. She probably won't know that I am the most terrifying person in this house.
