I am a Gao Fushuai Villain - Chapter 571:

Feng Lingxi was the traditional family’s head mistress – a person with a charismatic yet sly personality with the ability to attract people easily to her side, and having the potential to take someone’s soul away. Crossing across boundaries from a decade ago to now, a world that gives woman full respect and acknowledgement….

Don’t be fooled by her, because she was someone who would act obediently in front of a crowd but, stabs them in the back when necessary! Disguising as someone that would gain her trust and belief! That was why the Emperor of Xian started doting on her, allowing her to become absurdly daring to do whatever she liked. This made the Empress speechless to tears.
That would be the cause of the kingdom’s downfall in the near future…

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…

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!
