After Our Marriage of Convenience, We Couldn’t Hide the Secret Baby

Both leads are virgins + seven-year age gap + powerful man bows to love + fatherly, nurturing romance [The heroine seems innocent but is secretly cunning. By the end, she can easily bring to heel the man she once loved so desperately!] The “chubby girl” slimmed down and married the domineering CEO she had a one-night stand with four years earlier, under a marriage contract. Six months later, Fu Yanzhou said, “Song Tang, let's get divorced.” He was seven years older than Song Tang and didn't want to hold her back any longer. Song Tang thought he didn't love her. After grieving, she signed the divorce papers. Not long after the divorce, Fu Yanzhou discovered by chance that he had a son who was over three years old. The boy's mother was a middle-aged woman. Fu Yanzhou couldn't believe that the person he'd slept with all those years ago had been an old woman. An old woman who was fat and overweight, at that! He couldn't accept it at first, but he had no choice but to take responsibility as a father. Until one day... Fu Yanzhou heard his son call his ex-wife “Mommy” with his own ears. Back then, Song Tang insisted on having the baby. To keep it from affecting her future, her parents used the name of her aunt, Song Xiuli, throughout the pregnancy and delivery. Inside a black Maybach, the man dropped to one knee, eyes red, and begged her: “Tangtang, I was wrong. Let's get married again!”
