[Goofy, domineering big sister × obsessive, villainous puppy-like boy]
He Yunxi, a domineering CEO, transmigrates into a book and becomes a busty, brainless, villainous female character. According to the plot, she will keep bringing disaster upon herself, rack her brains to frame the heroine, and ultimately help the heroine and hero find their happy ending, before meeting a tragic end. The transmigration-into-a-book System tells her to save the villainous younger brother and prevent him from turning evil. Everything else is up to her. From then on, He Yunxi leads the villainous younger brother on a winning streak, slapping the hero's face and tearing into the scheming heroine. But can someone tell her: she's completed all the missions, so why is the villainous younger brother still glued to her? She calls the System for help, but who knows where it has gone off to have fun…
