Best Friends Transmigrate into a Book, Become Mother-in-Law and Daughter-in-Law, While Father and Son Climb Through the Window in Every Which Way

A sweet little treat, no angst, and easygoing everyday life. My best friend and I transmigrated together into the bodies of doomed supporting characters. I'm the mother-in-law, and she's the daughter-in-law. By day, I dish out slaps and scold my son until he doesn't dare talk back. She gives her son a cold look and says sarcastically, “So it turns out it was all my fault...” At night, we share a bed, crack melon seeds, and watch through the window as the father and son discuss all sorts of ways to sneak into bed with us. General Dad: “Keep your wife in line. Don't let her corrupt your mother.” Scheming Son: “Father, you should say that to Mother. If she invokes filial duty, Wan'er will have no choice but to obey.” “Three, two, one, go!” The moon shines high as the bed rocks without stopping~ ＊ My best friend and I are living the high life as noblewomen, but then the heroine shows up with her mother. Oh no! According to the original plot, once the heroine appears, our lives are on a countdown. For the sake of our lives, stay away from the heroine! Divorce. We have to get divorced! But those two scoundrels, father and son, refuse? Did we spend this whole year doing nothing? We have the imperial decree in hand. What stray dogs are barking? Throw them out. General Dad lands two solid punches. “You're a grown man, yet you grin at every woman and chase after them!” Scheming Son: “Father, I'm nothing compared to you. You had a mature beauty keeping you company in a pavilion in the rain.” - Couples in this story: A proud, flirtatious little troublemaker VS a rugged, fierce general who says one thing and means another A Sister Su with Lin Daiyu's temperament VS a handsome gentleman with the heart of a cunning fox
