The Stand-In Supporting Actress Is So Over the Top

The spoiled, high-maintenance heiress transmigrates into a book, and the System tells her, "This is a melodramatic story about a wealthy family. The male lead loves the heroine, the second male lead loves her too, and even the seemingly refined but secretly scheming villain admires her. You, meanwhile, are just a female cannon-fodder character. You play the role of the lowly stand-in for the male lead's beloved, his white moonlight. When the real deal comes back, you're kicked out, become a laughingstock to everyone, and end up broken and miserable for love."

"Until the plot is over, you can't break character."

Yu Jiao: "In your dreams. Hmph!"

The heiress is furious. She turns around and rips out all the chamomile the male lead planted in the garden for his white moonlight, replacing it with gorgeous red roses in full bloom.

She tosses every piece of clothing and jewelry in her wardrobe, replacing it all with designer couture, jewelry, luxury bags, and shoes.

And she casually sleeps with the alluring villain.

System: ???

Male lead: ???

The male lead comes back, ready to teach this insufferable, unbearably arrogant woman a lesson, but everyone holds him back. "What could the heiress possibly have done wrong? She was only trying to surprise you."

Later,

The System says, "Heiress, here's the situation. The second male lead doesn't want to protect the heroine anymore. He wants to protect you. The villain doesn't want to admire the heroine anymore. He wants to openly claim his place and marry you... As for the male lead, his eyes are red and his fists clenched as he mutters, 'I was the one who met you first...'"

Later still,

Under the spotlight, with the whole world watching,

Yu Jiao is at a launch event with a top international fashion designer when she suddenly furrows her brow slightly and looks down at her toes.

Everyone watches as the elegant, aloof man in the camera frame follows her gaze. His brow twitches, then he takes out a handkerchief, bends down, and wipes a speck of dust from the tip of her shoe.

Everyone: Heiress x young master forever!

Theme: Face difficulties without fear, rise to the challenge, uphold core values, and strive to be a good, civilized young person.
