The Undercover Heir is Actually Tycoon's Secret Girlfriend Novel

Rong Zhi spent eighteen years in a rural village, unaware she was switched at birth. Poverty and hardship defined her childhood until her biological parents arrived to reclaim her as the lost daughter of Beijing's prestigious Rong Family.

Her parents issued stern warnings: absorb your siblings' lessons, avoid scandal, and never embarrass the family name.

Rong Zhi accepted with a bright smile, but what unfolded defied everyone's expectations. The ignorant country girl they mocked became Beijing's most formidable figure—the one who controlled everything.

Confused whispers spread: This isn't how this was supposed to go.

When the Bai Family Head returned to China, powerful families tensed with anxiety. Only one member of the Rong household remained unbothered: Rong Zhi.

At an elite gathering, guests witnessed the impossible. The man at the world's apex—Mr. Bai—lowered himself to slip high heels onto a woman's feet. She stood barefoot on his shoes, wearing an emerald cheongsam, her dark hair flowing.

"Such a princess," he said, resignation in his voice.

"I am a princess, and you have no say in it," she replied, arrogant and familiar.

The crowd froze. That face. That tone. Third Master Rong?
