I Wore It with My Best Friend, and She Became My Mother-In-Law

I wore it with my best friend, and she became my mother-in-law I traveled back to ancient times and became a little daughter-in-law. I was sharpening my sword and fighting against the house. But I was horrified to discover that the evil mother-in-law who regarded me as a thorn in my side was actually my best friend in modern society. She handed me a cup of tea with a smile on her face and said, "I heard that you want to defeat me and take charge of your own business?" I immediately knelt down and said, "Boss, I was wrong! Wouldn't it be nice for us to join forces and watch a show?" From then on, the painting style of Hou Mansion changed drastically. She was responsible for making trouble, and I was responsible for fanning the flames and sending my cousin who wanted to crawl into bed into the farm to grow potatoes. Until one day, the cold-faced general who had been guarding the border all year round returned home. He looked at his arrogant and domineering mother, and then at me who was pretending to be powerful, with a deep look in his eyes: "You two, are you hiding something from me?"
