She Is the Older Brother of the Wicked Female Supporting Character

Zheng Ying transmigrates into a melodramatic household-intrigue drama, not as the female lead or a supporting character, but as the frail older brother of the wicked supporting female character.

Her mission is to change the wicked supporting female character's [Misfortune Score] and cure her of her love-brain.

She gets hit by the plot the moment she transmigrates: the wicked supporting female character drugs the male lead to force herself on him, only for the female lead to switch him out for the villain...

Known fact one: The drug is a knockout potion. The wicked supporting female character and the villain are both knocked out and sleep through the night. Nothing happens, but the supporting character's father catches them in the act and wants to beat her to death to preserve the family's reputation.

Known fact two: The villain turns evil because of this, later ascending the throne and becoming a tyrant who kills the wicked supporting female character's entire family, including her older brother, Zheng Ying.

Hahaha! After getting hit by the plot, Zheng Ying decides to hit everyone else right back!

First, she slaps the supporting character's father: What honor? What family reputation? You sneak off to meet maids at Taoist temples and have sex in broad daylight. Did you think about honor and family reputation then, Father?

Then she slaps the villain: You turn evil just because someone drugged you? Then you can abduct and force her sister into marriage!

Then she slaps the female lead: You have a golden finger, so go become emperor! Why fight your own sister over that cursed male lead?

Then she slaps the male lead for good measure: Why act so high and mighty? It's your good fortune that my sister likes you! Sell him off! Sell them all off!

Finally, she slaps her foolish younger sister, the wicked supporting character: Get a grip, love-brain! If you have energy to spare, go dig up some wild vegetables!

Zheng Ying wreaks havoc all the way to the end. She never expected to complete her mission and become the richest merchant and an imperial business magnate, but everyone's mental state is a little off...

The wicked supporting female character becomes obedient and clingy, and no longer wants to marry. She only wants to stay by her brother's side for the rest of her life.

The female lead with a golden finger dumps the male lead and becomes the first female official. She asks Zheng Ying resentfully, "If I weren't your sister, would you..."

Even the villain, after ascending the throne, starts sneaking into her room and asking her with a strange look, "What did you put in my drink, brother-in-law? I feel so hot..."

Zheng Ying, exasperated, says: First, I'm a woman. Second, did you all enjoy getting slapped that much?

#How did I go from being the most hated after going berserk to becoming everyone's favorite?#

P.S. She's a woman disguised as a man, and the female lead is a woman. It's a conventional boy-girl romance, with no yuri or BL.
