Lin Wan transmigrated into a book and became the stepmother of the male lead. Her husband was an undisputed big shot in commerce and was cold, decisive, and ruthless. Her stepsons were each more eccentric and difficult than the other… until they took part in a variety show as a family. Five families were competing, each of which was perfectly harmonious…

Except for Lin Wan’s family. Naturally, they were the control group once the variety show aired. Every other family would have scenes of the parents cooking and the children helping adorably, a picturesque sight of family harmony. On the other hand, Lin Wan and her three stepsons ignored each other as they had crackers and ham for their dinners amidst an eerie silence. At night, while the other families went out happily stargazing and moon-watching, Lin Wan and her stepsons told each other horror stories, leaving the viewers petrified! Netizens were flaming as they watched, but they soon noticed that the control group was changing…

Even though the eldest son insisted that he disliked his stepmother, he sneaked off to buy her a scarf! The second son declared his favorite person was his father but voted for his stepmother instead! The third son was also caught putting his stepmother’s favorite candy below her pillow! The netizens were shocked, but it’s true: the tsundere stepsons were extraordinarily close with their stepmother!
