[Another novel in my collection has enough chapters to binge: "The Supporting Female Character Just Wants to Live Her Life Well [Book Transmigration]"] Su Mei, a minor internet celebrity, transmigrates into a melodramatic romance novel. What? I'm the male lead's stepmother? Huh? I'm a fake stepmother? [Basic Information] Name: Su Mei Gender: Female Age: 23 Identity: The late chairman of the Gu Group's close female companion 1. Sweet, sweet, sweet (don't nitpick the details out of context). 2. [Important] The heroine is just a decorative woman kept around by the male lead's scumbag father. They have no actual relationship, either biologically or legally, so in the original novel, the heroine and male lead have no actual relationship either. 3. The heroine lets loose in front of other people but is ridiculously timid in front of the male lead. The male lead is a cold, abstinent CEO in public and a 360-degree, all-around sweetheart at home. ------Recommendations------ 1.
