Qiao Mu knew that escaping now was the best solution. If she was locked up and waited for her father to come back, Yu Tingyun's disguise would definitely make her an indelible criminal.
It wasn't that she hadn't been grounded before. When she was young, Qiao Ya deliberately locked her in her room for an entire day and starved her for the entire day. Yu Tingyun had seen everything. It could be said that everything Qiao Ya did in the past was caused by Yu Tingyun.
No matter how evil a ten-year-old child was, what could he do?
Yu Tingyun was secretly hinting at Qiao Ya. When Qiao Ya did that, Yu Tingyun pretended to be angry and lectured Qiao Ya.
With Qiao Ya's temper, she would always blame Qiao Mu for the scolding after she was lectured by Yu Tingyun. In the future, she would treat Qiao Mu even worse.
Yu Tingyun was a hypocrite, and no one except Qiao Mu would understand her true nature!
