Mommy's Cover Has Been Blown

Five years ago, Yan Liang was sent to a mental hospital by her father, and five years later, she was brought back to marry the Pei family's head, Pei Jingyuan, who had a twisted innate disability. 
She originally thought that her life after marriage would not be easy, but she did not think that she would be hugged by a cute baby. 
"Mommy, sleep with me today. "
"Mommy, you're so awesome! Better than Daddy!"
"Mommy, I don't think Daddy is good enough for you. Let me find you a better man!"
"You dare!" Pei Jingyuan couldn't bear it any longer and kicked his son out of the bedroom. He closed the door behind him and put Yan Liang in the corner. He gritted his teeth and said, "From now on, you are not allowed to spend more than an hour alone with him!"
Yan Liang,. . . "" That is your biological son.
